DVD drive as an inportant part for computer


DVD drive is now an important part for a computer.We mean dvd drive is
a high-density compact disk for storing large amounts of data, especially high-resolution audio-visual material.
DVD, also known as "Digital Versatile Disc" or "Digital Video Disc," is a popular optical disc storage media format. Its main uses are video and data storage. Most DVDs are of the same dimensions as compact discs (CDs) but store more than six times as much data.
Creation time:
In 1993, two high-density optical storage formats were being developed; one was the MultiMedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density (SD) disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC.
High-density double-sided compact disc that can store up to 17 gigabytes of digital data-roughly the equivalent of 24 CDs. Although believed to be a better medium for distributing feature-length films than videocassettes, less than 1% of U.S. Households currently has a DVD video player. DVDs are primarily used to store encyclopedias and interactive magazines and games. It is expected that DVD-ROM will eventually replace CD-ROM for storing audio, video, and text data.
