Laserdisc player

A Laserdisc player is an electro-mechanical device designed to play video (analog) and audio (analog or digital) stored on Laserdisc. Laserdisc was the first optical disc format marketed to consumers; it was introduced by MCA DiscoVision in 1978.

From 1978 until 1984, all Laserdisc player models read discs by using a helium–neon laser tube. In 1984, Pioneer Corporation introduced the first consumer player with a solid-state laser diode. This model, the Pioneer LD-700, was also the first Laserdisc player with a front-loading disc bay instead of a top-loading one. Pioneer became the market leader in Laserdisc technology.
