DVD full form digital versatile disc or digital video disc
After the futuristic-looking CD (Compact Disk) took the audio market by storm-consigning the humble cassette tape to the back of a billion cupboards-it was only a matter of time before technological wizards set their sights on abolishing the VHS tape.
Although the technology for LaserDisc already existed it never really took off in the way that CD technology did and so the market for a compact digital video disc was still very much open. The first proposals for high-density CD were put forward in 1983, leading to the creation of two competing formats. Electronic powerhouses Sony and Philips led their collected investors forward with the MMCD format going head to head with industry giants Toshiba, Masushita and Time Warner’s effort the SD. Then, in 1995, a combined effort-known as the DVD-was officially announced and consequently developed by a consortium of ten companies.
The DVD was capable of storing two hours of high quality digital video, eight tracks of digital audio and thirty two tracks of subtitle information as well as offering the practical benefits of being lightweight, compact, easily rewind able and durable. Dual-layer DVDs later doubled this capacity and two sided DVDs (which can be flipped over like vinyl LPs) doubled it again without creating needless bulk.
Although DVD is often cited as being as acronym for digital video disc or digital versatile disc, the official lie on it-as stated in 1999 by the 250 company members in the DVD Forum-is that it is simply a three letter name.
DVD full name is digital versatile disc or digital video disc. DVD is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The medium DVD can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.
