Recorders, Digital Versatile Disk
Definition : Recorders designed to store large amounts of digital data, video, and/or audio signals in an optical disk (digital versatile disk [DVD]). These recorders usually consist of an electromechanical device that includes external connectors to provide links to video cameras or other sources of video, audio signals (e.g., cable boxes, camcorders) or data; an optical writer consisting of a red light laser (typically 650nm wavelength); data processors; controls; and an slot to place a DVD. The recorders may include an analog/digital converter and other accessories such as microphones. DVD recorders usually have playing capabilities (using a laser reader) both for video and audio signals, either through integral amplifiers, displays, and loudspeakers (typical in portable players) or by providing output to video reproduction systems (e.g., monitors or television sets). Most DVD recorders have capabilities to play audio and video optical compact discs (CDs). Some can also provide output for high-definition television sets (i.e., up-conversion to 720 or 1080 lines). DVD recorders are available in tabletop, rack mounted, and portable versions.
