Dvd (digital Video Disc / Digital Versatile Disc)

Categories: Operation and Production,

An optical disc format that has improved capacity and bandwidth over its predecessor, the CD-ROM. It consists of microscopic reflective pits that a laser scans. The displacement of the laser beam allows the drive to work out if the pit represents a 1 or a 0 in binary code. Commonly used for distributing movies and video games, but is about to be superseded by higher capacity high definition formats.
