LaserDisc

An early optical videodisc technology for movies and training. Introduced in 1978, Pioneer LaserDisc players came out two years later and became the choice for commercial use. Never widely used, by the 1990s, LaserDiscs were superseded by Video CDs and then DVDs.

LaserDiscs Were Analog
Based on LaserVision (combination of MCA Disco-Vision and Philips Video Long Play), the LaserDisc recorded an analog composite video signal on a continuous, spiraling track (see CLV). Each side of the 12" platter held one hour of video in 108,000 frames.

For interactive training and games, a circular track held one video frame (see CAV), and 54,000 frames provided 30 minutes of video per side. The first LaserDiscs recorded analog audio, but digital audio was later added, and newer players supported multiple language soundtracks. See CED.
