57 Sentences With "optical disk" | Random Sentence Generator

Apple built the Air not for 2008, but for later when wireless networking was ubiquitous and optical disk drives were all but relics.

Even when companies do sell physical media, users would still need to download the latest version of the software, as opposed to the one that's on the optical disk.

Screenshot: Merriam-WebsterYours truly was born in 1977, which apparently saw the first use of many phrases common in tech today including 'optical disk,' 'Moore's Law,' 'karaoke,' and 'text message.

Sure, it was thin, said bloggers at the time, but it lacked an optical disk drive and relied too much on wireless connectivity since it didn't have an ethernet port.

Sure, I sometimes miss the DVD player, but thanks to the loss of DVD players in laptops I haven't looked at an optical disk in years and have figured out better solutions.

But for more money (pricing not yet available), you can add different modules like the HP Audio Module for speakers, an optical disk drive, and different top panels with wireless charging or touch-sensitive buttons for video conferencing.

LS-R, or the Layer-Selection-Type Recordable Optical Disk, is the term coined by Hitachi in 2003K. Kojima, M. Terao, Proc. ODS SPIE vol. 5069 (2003), 300.

The HI disk of NGC 4302 is truncated to within the optical disk to the south of the galaxy. This truncation appears to be the result of ram-pressure.

Ridenour led the development of airborne microwave radar nicknamed "Micky" which allowed bombing through clouds. Along with Gilbert W. King, Edwin L. Hughes, and George W. Brown, Ridenour patented an information storage system which combined optical disk storage of large capacity and a magnetic drum memory of low capacity. The write-once-read-many optical disk memory would be updated monthly, and recently changed data is held on the re-writable magnetic drum memory.

Other modchips, such as the XenoGC and clones for the Nintendo GameCube, invoke a debug mode where security measures are reduced or absent (in which case a stock Atmel AVR microcontroller was used). A more recent innovation are optical disk drive emulators or ODDE, which replace the optical disk drive and allow data to come from another source bypassing the need to circumvent any security. These often make use of FPGAs to enable them to accurately emulate timing and performance characteristics of the optical drives.

Intel Corporation defined form factor and interconnection standards for notebook computer components, including "Barebones" (chassis and motherboard), hard disk drive, optical disk drive, LCD, battery pack, keyboard, and AC/DC adapter. These building blocks are primarily marketed to computer building companies, rather than DIY users.

UMD disc front The Universal Media Disc (UMD) is a discontinued optical disc medium developed by Sony for use on their PlayStation Portable handheld gaming and multimedia platform. It can hold up to 1.8 gigabytes of data and is capable of housing video games, feature-length films, and music. UMD was the trademark of Sony Computer Entertainment for their optical disk cartridge (ODC).

Optiarc is a brand of optical disc drives and solid-state drives. It is owned by a US-based Vinpower Digital, Inc. Initially Optiarc was established on April 3, 2006 as a joint venture between Sony (55% shares) and NEC (45% shares). The company, named Sony NEC Optiarc, focused on manufacturing optical disk drives primarily for the OEM desktop and notebook PC markets.

In 1969 four former IBM engineers—Jesse Aweida, Juan Rodriguez, Thomas S. Kavanagh, and Zoltan Herger—founded the Storage Technology Corporation. The headquarters was in Louisville, Boulder County, Colorado. In the 1970s, StorageTek launched its Disk Products division. After a failed attempt to develop an IBM-compatible mainframe, and an optical disk product line, the company filed for Chapter 11 bankruptcy protection in 1984.

Bonded neo powder is incorporated into numerous end market applications that utilize bonded neo magnets. These products are primarily motors and sensors used in a range of products, including computer and office equipment (e.g., hard disk drives and optical disk drive motors and fax, copier and printer stepper motors), consumer electronics (e.g., personal video recorders and mp3 music players), automotive and industrial applications (e.g.

Defragmentation is advantageous and relevant to file systems on electromechanical disk drives (hard disk drives, floppy disk drives and optical disk media). The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments.

To transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.

Netbooks are small laptops, with screen sizes between approximately 7 and 12 inches and low power consumption. They use either an SSD (solid state disk) or a HDD (hard disk drive) for storage, have up to 2 gigabytes of RAM (but often less), lack an optical disk drive, and usually have USB, Ethernet, WiFi and often Bluetooth connectivity. The name emphasizes their use as portable Internet appliances.

The digital acceleration data is transferred to optical disk memory for ground analysis and downlinked to the ground for near-real-time analysis. Each accelerometer has a mass suspended by a quartz element is such a manner to allow movement along one axis only. A coil is attached to the mass and the assembly is placed between two permanent magnets. An applied acceleration displaces the mass form its resting position.

The atomic hydrogen is detected mostly within the limits of the optical disc but also extends one and a half times the radius of the optical disk. The hydrogen forms streaming motions near the spiral arms. The gas features two anticyclonic and four cyclonic vortices, rotating with the spiral pattern. The anticyclones are caused by the differential rotation and the cyclones are the result of a high amplitude in the density wave.

This movement provided some of the impetus for the rise of digital history in the 1990s. The more recent roots of digital history were in software rather than online networks. In 1982, the Library of Congress embarked on its Optical Disk Pilot Project, which placed text and images from its collection on to laserdiscs and CD-ROMs. The library started offering online exhibits in 1992 when it launched Selected Civil War Photographs.

In its earlier stage, it mainly focused on ultra-low power consumption such as 0.5 mW/MIPS. V850 has been widely used in variety of applications including: optical disk drives, hard disk drives, mobile phones, car audio and inverter compressors for air conditioners. But today, new microarchitectures are mainly toward high performance and high reliability with such as dual-lockstep redundant mechanism for automotive industry. Nowadays, V850 Family and RH850 Family are comprehensively used in a car.

Radio observations at the 21-cm hydrogen line show the gaseous disk of M63 extends outward to a radius of , well past the bright optical disk. This gas shows a symmetrical form that is warped in a pronounced manner, starting at a radius of . The form suggests a dark matter halo that is offset with respect to the inner region. The reason for the warp is unclear, but the position angle points toward the smaller companion galaxy, UGC 8313.

Tellurium monoxide was first reported in 1883 by E. Divers and M. Shimose. It was supposedly created by the heat decomposition of tellurium sulfoxide in a vacuum, and was shown to react with hydrogen chloride in a 1913 report. Later work has not substantiated the claim that this was a pure solid compound. By 1984, the company Panasonic was working on an erasable optical disk drive containing "tellurium monoxide" (really a mixture of Te and TeO2).

This optimizes the linear velocity of the glass master, giving precise pit lengths to eliminate time jitters, controlled by an extremely precise rubidium clock. All CDs are finally stamped directly from this glass master. XRCD2 and XRCD24 are improved versions of the original XRCD process. XRCD2 is the first to record to a magneto-optical disk via the digital K2 regenerator, while XRCD24 upgrades the original music signal's bit depth signal from 20 to 24 bits.

This front-edge position makes extension out the back to an external device even more difficult. Ribbon cables are poorly shielded, and the standard relies upon the cabling to be installed inside a shielded computer case to meet RF emissions limits. External hard disk drives or optical disk drives that have an internal PATA interface, use some other interface technology to bridge the distance between the external device and the computer. USB is the most common external interface, followed by Firewire.

The Digitronix PC (DTX PC) of 1992 is an inexpensive OEM personal computer that can also serve as a business capable workstation or a clustered file server. It boasted 100 megabytes of ram, an HDTV monitor and optical disk storage, possibly based on the NeXTcube's magneto-optical drive. It also had built in compatibility with NTSC\PAL formats and had built in composite video out, as well as advanced digital audio and video editing capacity on-chip, possibly as coprocessors similar to the Amiga.

The AppleCD SC was the first CD-ROM by Apple Computer Company, introduced in 1988. It originally contained a fan but in 1990 they removed it because it was unneeded and attracted dust onto the optical disk head which could cause problems. It uses a front-loading caddy 1x CD-ROM and is only capable of Read Only Media. This accessory device was only able to read compact discs up to a 650 MB capacity in five formats, CD-Audio, CD-ROM, HFS, ProDOS, and High Sierra.

The usual purpose of stubbing files is to move data from an expensive high-speed storage device such as a computer's hard drive to lower cost storage such as a magnetic tape, or an electro- optical disk, while not requiring users to know how to use specialised storage software to retrieve the data. It also allows a system manager to enforce the use of low cost storage when users would prefer to store their files on the highest availability, and highest cost, media supplied.

The chromosphere was directly imaged by the Faint Object Camera on board the Hubble Space Telescope in ultraviolet wavelengths. The images also revealed a bright area in the southwest quadrant of the disk. The average radius of the chromosphere in 1996 was about 2.2 times the optical disk (~) and was reported to have a temperature no higher than . However, in 2004 observations with the STIS, Hubble's high-precision spectrometer, pointed to the existence of warm chromospheric plasma at least one arcsecond away from the star.

During Apple's 2005-2006 transition from PowerPC to Intel processors, the company announced and made available an analogous prototype Macintosh computer for developers. Also called "Developer Transition Kit", the computer identified itself as "Apple Development Platform" (ADP2,1), and consisted of a 3.6 GHz Intel Pentium 4 processor, 1 GB DDR2 RAM, 160 GB SATA hard disk drive, and optical disk drive in a Power Mac G5 case slightly modified with an altered cooling system. Connectivity included USB 2.0, FireWire 400, and Gigabit Ethernet. Software included Xcode 2.1 and a version of Mac OS X 10.4.

Large quantities of individual magnetic tapes, and optical or magneto-optical discs may be stored in robotic tertiary storage devices. In tape storage field they are known as tape libraries, and in optical storage field optical jukeboxes, or optical disk libraries per analogy. The smallest forms of either technology containing just one drive device are referred to as autoloaders or autochangers. Robotic-access storage devices may have a number of slots, each holding individual media, and usually one or more picking robots that traverse the slots and load media to built-in drives.

NeXTStep monochrome (2 bit) NeXTStep 1.0 used a monochrome icon resembling a spinning magneto-optical disk, whose drive was quite slow and so was a common reason for the wait cursor to appear. NeXTStep color (12 bit) When color support was added in NeXTStep 2.0, color versions of all icons were added. The wait cursor was updated to reflect the bright rainbow surface of these removable disks, and that icon remained even when later machines began using hard disk drives as primary storage. Contemporary CD Rom drives were even slower (at 1x, 150 kbit/s).

NGC 5861 is an intermediate spiral galaxy in constellation Libra. It is located at a distance of circa 85 million light years from Earth, which, given its apparent dimensions, means that NGC 5861 is about 80,000 light years across. Center image by Hubble Space Telescope The galaxy features two long spiral arms that dominate the optical disk. The one arm can be traced from its beginning at the center for nearly one and a half revolutions without branching, whereas the other starts to form fragments after one revolution, forming a moderately chaotic pattern.

The IdeaCentre K Series desktops from Lenovo are described by the manufacturer as being gaming-oriented desktops. Typical features on the desktops include mid-range to high-end processors, discrete graphics cards, multiple hard disk drives, multiple RAM DIMMS, multiple USB ports, and multiple optical disk drives. The K Series desktops also come with a physical switch on the CPU that allows users to shift between different levels of processing power. For example, the K330 offered red for high performance, blue for moderate performance, and green for less processing- and resource-intensive tasks.

If analog, the source material is first converted to digital via JVC's K2 20-bit or 24-bit analog-to-digital converter. The musical information is next encoded on a magneto-optical disk for transport to JVC's Yokohama manufacturing plant, where jitter reduction is applied. The musical signal on the disk is down-converted to 16-bit through a K2 "super-coding" process. This 16-bit signal is eight-to-fourteen modulation-encoded (EFM-encoded) before going through a proprietary "Extended Pit Cut" DVD K2 laser technology to produce a glass master.

Hyland Software was established in 1991 by Packy Hyland Jr. He met with members of The Necedah Bank to discuss its data processing and how electronic information technology could reduce printing costs by storing daily reports directly to optical disk. Packy Hyland created the first version of OnBase for The Necedah Bank, which became Hyland Software's first customer. Because OnBase was originally created for a bank, a majority of Hyland Software's customers were in the banking industry until recently when the healthcare providers found value from ECM technologies.

When examined at the 21 cm wavelength Hydrogen line, NGC 4921 was found to be strongly H I deficient, indicating it is low in hydrogen. The distribution of hydrogen has also been deeply perturbed toward the SE spiral arm and is less extended than the optical disk of the galaxy. This may have been caused by interaction with the intergalactic medium, which is stripping off the gas. On May 4, 1959, a supernova explosion was observed in this galaxy by M. L. Humason using a Schmidt telescope at the Palomar Observatory.

Sega, however, was extremely successful in this generation and began a new franchise, Sonic the Hedgehog, to compete with Nintendo's Super Mario series of games. Several other companies released consoles in this generation, but none of them were widely successful. Nevertheless, there were other companies that started to take notice of the maturing video game industry and begin making plans to release consoles of their own in the future. While as with prior generations, game media still continued to be primarily provided on ROM cartridges, though the first optical disk systems, such as the Philips CD-i, were released to limited success.

Alternatively, temporal coherence can be used to produce pulses of light with a broad spectrum but durations as short as a femtosecond ("ultrashort pulses"). Lasers are used in optical disk drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, semiconducting chip manufacturing (photolithography), and free-space optical communication, laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. They have been used for car headlamps on luxury cars, by using a blue laser and a phosphor to produce highly directional white light.

Like many other spiral galaxies of the Virgo Cluster (e.g. Messier 90), Messier 58 is an anemic galaxy with low star formation activity concentrated within the galaxy's optical disk, and relatively little neutral hydrogen, also located inside its disk, concentrated in clumps, compared with other galaxies of similar morphological type. This deficiency of gas is believed to be caused by interactions with Virgo's intracluster medium. Messier 58 has a low-luminosity active galactic nucleus, where a starburst may be present as well as a supermassive black hole with a mass of around 70 million solar masses.

Fragmented data occurs if data is stored in clusters. The Court provided the guidance that, in general, the first three classes may be considered accessible while the last two may be considered inaccessible. In the specific case before the Court, it was found that there existed both accessible and inaccessible data, with active e-mail files falling into the first category, and e-mails saved to optical disk falling into the second or third category. Since backup tapes are a form of inaccessible data, the Court found it appropriate to consider cost-shifting for the recovery of e-mails from those tapes.

Jigdo (a portmanteau of "Jigsaw" and "download") is a utility typically used for downloading to piece together a large file, most commonly an optical disk image such as a CD, DVD or Blu-ray Disc (BD) image, from many smaller individual constituent files. The constituent files may be local and/or retrieved from one or more mirror sites. Jigdo's features are similar to BitTorrent, but unlike BitTorrent, Jigdo uses a client-server model, not peer- to-peer. Jigdo itself is quite portable and is available for many UNIX and Unix-like operating systems, and is also available for Microsoft Windows.

An optical disk recorder encodes (also known as burning, since the dye layer is permanentely burned) data onto a recordable CD-R, DVD-R, DVD+R, or BD-R disc (called a blank) by selectively heating (burning) parts of an organic dye layer with a laser. This changes the reflectivity of the dye, thereby creating marks that can be read like the pits and lands on pressed discs. For recordable discs, the process is permanent and the media can be written to only once. While the reading laser is usually not stronger than 5 mW, the writing laser is considerably more powerful.

The base 30GB model sold for $158,000 with one 30GB optical disk library unit and one 760MB magnetic disk drive. By making use of high capacity and comparatively inexpensive (for that time) optical storage the Epoch-1 provided high storage capacity at substantially lower cost than all-magnetic file servers. Epoch's second product, EpochBackup, included automatic scheduling, online backup and volume management features for Unix-based client workstations from a number of manufacturers, including DEC, IBM, Hewlett Packard, Silicon Graphics and Sun Microsystems. In late 1990 Epoch released versions of its Renaissance storage management products for Sun, HP, and MIPS Technologies Unix workstations.

An example of a ray-traced image that typically takes seconds or minutes to render Computer-generated image (CGI) created by Gilles Tran Animations for non-interactive media, such as feature films and video, can take much more time to render. Non real-time rendering enables the leveraging of limited processing power in order to obtain higher image quality. Rendering times for individual frames may vary from a few seconds to several days for complex scenes. Rendered frames are stored on a hard disk, then transferred to other media such as motion picture film or optical disk.

In the 1980s though, the discovery of germanium-antimony-tellurium (GeSbTe) meant that phase-change memory now needed less time and power to function. This resulted in the success of the rewriteable optical disk and created renewed interest in the phase-change memory. The advances in lithography also meant that previously excessive programming current has now become much smaller as the volume of GeSbTe that changes phase is reduced. Phase-change memory has many near ideal memory qualities such as non-volatility, fast switching speed, high endurance of more than 1013 read –write cycles, non-destructive read, direct overwriting and long data retention time of more than 10 years.

Conway began his career in October, 1977, when he joined the staff of the Gerald R. Ford Presidential Library as an archivist and worked there for 10 years. Between 1987 and 1989, Conway worked for the Society of American Archivists as a Preservation Program Officer. From January 1990 to May 1992, he worked for the National Archives and Records Administration in various research positions. It was here that he conducted research on the Use of Archives and a review of how government agencies implement digital imaging and optical disk technology. Conway also served successfully as Preservation Program Officer for the Society of American Archivists in Chicago in 1988 and 1989.

The first ISO/TC 97/SC 23 Meeting was held in Tokyo in 1985. The subcommittee had the title, “Optical disk cartridges.” After the creation of JTC1, ISO/IEC JTC 1/SC 23 held its first plenary in November to December 1988 in Maastricht, Netherlands. The subcommittee title was later changed a number of times up to its current title, “Digitally recorded media for information interchange and storage,” as of 2006. In 1989, ISO/IEC JTC 1/SC 23 adopted the File Formats standards maintenance from ISO/IEC JTC 1/SC 15 and was also merged with ISO/IEC JTC 1/SC 11, “Magnetic recording tape and disc,” in 2004.

ITE IT8212F 0812-DXS The IT8212, or more correctly the IT8212F, is a low-end Parallel ATA controller designed by ITE Tech. Depending on the implemented BIOS and configuration the IT8212F functions in either a RAID or an ATAPI mode, supporting up to four devices using dual channels. The raid mode only supports IDE Hard Disk Drives and includes RAID 0, RAID 1, Raid 0+1 and JBOD, along with a "normal" mode that essentially acts as a standard Hard Disk controller. Optical disk drives such as CD-ROM and DVD drives are supported by the ATAPI mode, which also supports Hard Disk Drives at the loss of all RAID functions.

It has been part of an ongoing effort to study its Cepheid variable stars. The outer arms appear blue due to the continuing formation of young stars and include a possible luminous blue variable with an absolute magnitude of −10. NGC 4414 is also a very isolated galaxy without signs of past interactions with other galaxies and despite not being a starburst galaxy shows a high density and richness of gas – both atomic and molecular, with the former extending far beyond its optical disk. NGC 4414 is a member of the Coma I Group, a group of galaxies lying physically close to the Virgo Cluster.

NGC 4216 is one of the largest and brightest spiral galaxies of the Virgo Cluster, with an absolute magnitude that has been estimated to be −22 (i.e.: brighter than the Andromeda Galaxy), and like most spiral galaxies of this cluster shows a deficiency of neutral hydrogen that's concentrated within the galaxy's optical disk and has a low surface density for a galaxy of its type. This explains why NGC 4216 is considered an anemic galaxy by some authors, also with a low star formation activity for a galaxy of its type. In fact, the galaxy's disk shows pillar-like structures that may have been caused by interactions with the intracluster medium of Virgo and/or with nearby galaxies.

This connector has no retaining screws to secure the connectors together, and ribbon cables are both inconveniently wide and somewhat delicate, so this connector style was primarily used for connections inside of a computer or peripheral enclosure (as opposed to connecting two enclosures to each other). Thus it is often called an "internal SCSI connector." This type of header was used in a typical desktop PC until around 2010, including the 40-pin (two rows of 20) version used for ATA fixed and optical disk drives. While the female connector is slotted such that a cable with a matching keyed male connector can not be inserted upside-down, some manufacturers (including Sun Microsystems) supplied internal cables with male connectors that did not have the key, allowing for incorrect (and possibly damaging) connections.

Research in the Department of Precision Instrument is divided to four main parts, led by its four research institutes: the Institute of Opto-electronic Engineering, the Institute of Instrument Science and Technology, the Engineering Research Center for Navigation Technology, and the Center for Photonics and Electronics. At the same time, the Department of Precision Instrument has three key laboratories: the State Key Laboratory of Tribology, the State Key Laboratory of Precision Measurement Technology and Instruments, and the Key Laboratory of High-accuracy Inertial Instrument and System. It also has two national engineering research centers, which are the National Engineering Research Center of Optical Disk and the CIMS National Engineering Research Center. ; The Institute of Opto-electronic Engineering The Institute of Opto-electronic Engineering (IOEE) was established in 1958.

The BBC Sound Archive keeps not only samples of various programmes and historical events, but also a comprehensive collection of wildlife recordings so that the correct animals or birds can be used in the backgrounds of films and dramas. In 1986 he left the BBC and took up the post of Conservation Manager and later become the Head of Sound Conservation at the National Sound Archive (now part of the British Library) which essentially performs much the same functions for sound recordings as the Library does for books and other publications. He was instrumental in effecting the move to digital archivingInitially done on Betamax or VHS video recorders, recording a digital audio signal instead of video (using the Sony PCM-F1). As time progressed research was done into other formats such as optical disk.

The Active Archive Alliance is a trade association that promotes a method of tiered storage which gives the user access to data across a virtual file system that migrates data between multiple storage systems and media types including solid-state drive/flash, hard disk drives, magnetic tape, optical disk, and cloud. The result of an active archive implementation is that data can be stored on the most appropriate media type for the given retention and restoration requirements of that data. This allows less time sensitive or infrequently accessed data to be stored on less expensive media, and eliminates the need for an administrator to manually migrate data between storage systems. Additionally since storage systems such as tape libraries have very low power consumption, the operational expense of storing data in an active archive is greatly reduced.

No-CD cracks have legal uses, such as creating backups of legally owned software (a user right by law in many countries) or avoiding the inconvenience of placing a CD or DVD-ROM in the drive every time the software is being used, although they can also be used to circumvent laws in many countries by allowing the execution of full versions of non-legally owned applications or time-limited trials of the applications without the original disc. In addition to cracked executable files or byte patchers, CD protection can sometimes be thwarted by producing a mini image containing only enough of the software's CD-ROM contents needed to bypass protection. This image can then be mounted with a disk image emulator such as Daemon Tools to "trick" the user's computer's Operating System (OS) into believing that said disk image is a physical optical disk inserted into a physical optical drive attached to the computer. As a side benefit, data from mounted disk images generally load much faster than a real disk would because the data is stored on the hard drive.
