DVDin full digital video disc or digital versatile discType of optical disc. The DVD represents the second generation of compact-disc (CD) technology. Like a CD drive, a DVD drive uses a low-power laser to read digitized (binary) data that have been encoded onto the disc in the form of tiny pits. Because it uses a digital format, a DVD can store any kind of data, including movies, music, text, and graphical images. DVDs are available in single- and double-sided versions, with one or two layers of information per side. Single-sided DVDs have become standard media for recorded motion pictures, largely replacing videotape in the home market. A double-sided, dual-layer version can store about 30 times as much information as a standard CD. DVDs are made in a ROM (read-only memory) format as well as in erasable (DVD-E) and recordable (DVD-R) formats. Though DVD players can usually read CDs, CD players cannot read DVDs. It is expected that DVDs will eventually replace CDs, especially for multimedia workstations. Digital Video DiscSee DVD.
