Videodisc

Videodisc (or video disc) is a general term for a laser- or stylus-readable random-access disc that contains both audio and analog 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. The first mainstream official Videodisc was the Television Electronic Disc (TED) Videodisc, and the newest is the 4K Ultra HD Blu-Ray Disc. As of September 2023, the active video disc formats are Blu-ray Disc, DVD, and in other regions because of the price difference from DVD, Video CD (VCD) and SVCD.
