What is DVD?
DVD stands for Digital Versatile Disk. It is a multi-purpose technology suited to both entertainment and computer uses. A DVD is identical in thickness (1.2 millimeters) and diameter (120 millimeters or 4.7 inches) to a standard Compact Disc, but that’s where the similarities end. The DVDs storage capacity is seven times that of a CD, with a 4.7-gigabyte capacity on a single-side/single-layer DVD. That’s the data-storage equivalent of a 133-minute movie, thus allowing 95 percent of all movies to fit comfortably on a single-layer DVD, eliminating the need for “flipping” the disc and leaving extra room for multiple audio, language, and subtitle tracks; bonus materials; menu screens; and other features unique to DVD. This capacity is nearly doubled (8.5 GB) on a single-side/dual-layer DVD, and quadrupled (17 GB) on a double-side/dual-layer DVD, allowing DVD to flourish not only as a movie-lover’s format, but as an amazingly flexible medium (DVD-ROM) for high-definition computer games and

DVD is movies on a shiny disc, and much more. It’s an optical disc storage technology for video, audio, and computer data. DVD is essentially a bigger, faster CD that can hold high-quality digital video, better-than-CD audio, pictures, and any other sort of digital information. DVD encompasses home entertainment, computers, and business information with a single digital format. It replaced laserdisc, videotape, many video game cartridge formats, and many CD-ROM applications. DVD has widespread support from all major electronics companies, all major computer hardware companies, and all major movie and music studios. With this unprecedented support, DVD became the most successful consumer electronics product of all time in less than three years of its introduction. In 2007, ten years after launch, there were over one billion DVD playback devices worldwide, counting DVD players, DVD PCs, and DVD game consoles. It’s important to understand the difference between the physical formats (such
