Videodisc
From Wikipedia, the free encyclopedia
Videodisc (or video disc) is a general term for a laser- or stylus-readable random-access circular disc that contains both audio and video signals recorded in an analog form. Typically, it is a reference to any such media that predates the mainstream popularity of the DVD format. Such formats include:
- MCA/Philips DiscoVision (early name for laserdisc format) (1978)
- Pioneer Corporation LaserDisc (1980)
- RCA SelectaVision brand of CED players and discs (1981)
- VHD, a videodisc format that was marketed predominantly in Japan by JVC (1983)
- Laserfilm, a videodisc format developed by McDonnell Douglas (1984)
- MovieCD, by SIRIUS Publishing, Inc. (1995?)
Unlike the battles between VHS and Betamax, there was no serious format war between early video disc formats as the LaserDisc proved to be technologically superior to all challengers of its time. Even the LaserDisc, though, failed to achieve much market traction against videotape, due to the latter's ability to allow consumer recording. Only with the introduction of the modern DVD format did a disc technology take hold for video. The modern DVD format also had little competition; only the short-lived DIVX format (not to be confused with the DivX video codec).
