Plextor
Plextor (styled PLEXTOR) ( zh, 浦科特; ) is a Taiwanese (formerly Japanese) consumer electronics brand, best known for solid-state drives and optical disc drives. Company The brand name Plextor was used for all products manufactured by the Electronic Equipment Division and Printing Equipment Division of the Japanese company ''Plextor Inc.'', which was a 100%-owned subsidiary company of ''Shinano Kenshi, Shinano Kenshi Corp.'', also a Japanese company. The brand was formerly known as TEXEL, under which name it introduced its first CD-ROM optical disc drive in 1989. The brand has been used for flash memory products, Blu-ray players and burners, DVD-ROM burners, CD-ROM burners, DVD and CD media, computer network, network hard disks, portable hard disks, digital video recorders, and floppy disk drives. The brand Plextor was in 2010 licensed to ''Philips & Lite-On Digital Solutions Corporation'', a subsidiary company of ''Lite-On, Lite-On Technology Corporation''. Therefore, all th ...

Optical Drive
In computing, an optical disc drive (ODD) is a disk drive, disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, while other drives can both read and record. Those drives are called burners or writers since they physically burn the data onto the discs. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives. Although most laptop manufacturers no longer have optical drives bundled with their products, external drives are still available for purchase separately. Drive types Some drives can only read data where as others can both read data and write data to writable discs. Drives which can read but not write data are "-ROM" (read-only memory) drives, even if they can read from writable formats such as "-R" and "-RW". Some drives have mixed read and wri ...

Double-density Compact Disc
The double-density compact disc (DDCD) is an optical disc technology developed by Sony and Philips using the same 780 nm laser wavelength as a compact disc. The format was announced in July 2000 and is defined by the ''Purple Book'' standard document. Unlike the compact-disc technology it is based on, DDCD was designed exclusively for data, with no audio capabilities. For a 12 cm disc, it doubles the original 650 MB to 1.3 GB capacity of a CD on recordable (DDCD-R) and rewritable (DDCD-RW) discs by narrowing the track pitch from 1.6 to 1.1 micrometers, and shortening the minimum pit length from 0.833 to 0.623 micrometers. The DDCD was also available in read-only format (DDCD-ROM). The specification allowed for both 12 cm and 8 cm discs, although an 8 cm DDCD disc was never released. The technology, released years after rewritable DVD technology, failed to acquire significant market share. The only DDCD recorder introduced was the Sony CRX200E. While the initial launch pric ...

Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format co-developed by Philips and Sony to store and play digital audio recordings. It employs the Compact Disc Digital Audio (CD-DA) standard and was capable of holding of uncompressed stereo audio. First released in Japan in October 1982, the CD was the second optical disc format to reach the market, following the larger LaserDisc (LD). In later years, the technology was adapted for computer data storage as CD-ROM and subsequently expanded into various writable and multimedia formats. , over 200 billion CDs (including audio CDs, CD-ROMs, and CD-Rs) had been sold worldwide. Standard CDs have a diameter of and typically hold up to 74 minutes of audio or approximately of data. This was later regularly extended to 80 minutes or by reducing the spacing between data tracks, with some discs unofficially reaching up to 99 minutes or which falls outside established specifications. Smaller variants, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GigaRec
CD-R (Compact disc-recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can only be written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs. History Originally named CD Write-Once (WO), the CD-R specification was first published in 1988 by Philips and Sony in the Orange Book, which consists of several parts that provide details of the CD-WO, CD-MO (Magneto-Optic), and later CD-RW (Re Writable). The latest editions have abandoned the use of the term ''CD-WO'' in favor of ''CD-R'', while '' CD-MO'' was rarely used. Written CD-Rs and CD-RWs are, in the aspect of low-level encoding and data format, fully compatible with the audio CD (''Red Book'' CD-DA) and data CD (''Yellow Book'' CD-ROM) standards. The Yellow Book standard for CD-ROM only specifies a high-level data format and refers to the Red Book for all physical format and low-l ...

CD-ROM
A CD-ROM (, compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains computer data storage, data computers can read, but not write or erase. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs). During the 1990s and early 2000s, CD-ROMs were popularly used to distribute software and data for computers and fifth generation video game consoles. DVDs as well as downloading started to replace CD-ROMs in these roles starting in the early 2000s, and the use of CD-ROMs for commercial software is now rare. History The earliest theoretical work on optical disc storage was done by independent researchers in the United States including David Paul Gregg (1958) and James Russell (inventor), James Russel (1965–1975). In particular, Gregg's paten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optical Disc
An optical disc is a flat, usuallyNon-circular optical discs exist for fashion purposes; see shaped compact disc. disc-shaped object that stores information in the form of physical variations on its surface that can be read with the aid of a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to be detected on the other side. Optical discs can store analog information (e.g. LaserDisc), digital information (e.g. DVD), or store on the same disc (e.g. CD Video). Their main uses are the distribution of media and data, and long-term archival. Design and technology The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track ...

Kioxia
Kioxia Holdings Corporation () is a Japanese multinational computer memory manufacturer headquartered in Tokyo, Japan. The company was spun off from the Toshiba conglomerate in June 2018 and gained its current name in October 2019; it is currently majority owned by Bain Capital which holds a 56% stake, while Toshiba holds a 41% stake. In the early 1980s, while still part of Toshiba, the company was credited with inventing flash memory. As of the second quarter of 2021, the company was estimated to have 18.3% of the global revenue share for NAND flash solid-state drives. Name Kioxia is a combination of the Japanese word '' kioku'' meaning ''memory'' and the Greek word '' axia'' meaning ''value''. History In 1980, Fujio Masuoka, an engineer at Kioxia predecessor Toshiba, invented flash memory, and in 1984, Masuoka and his colleagues presented their invention of NOR flash.
