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.

E & H T Anthony, a camera maker based in New York, marketed in 1898 a combination motion picture camera and projector called "The Spiral" that could capture 200 images arranged in a spiral on an 8 inch diameter glass plate, which when played back at 16 frames per second would give a running time of 13 seconds.

Theodore Brown patented in 1907 (UK patent GB190714493) a photographic disk system of recording approximately 1,200 images in a spiral of pictures on a 10 inch disk. Played back at 16 frames per second, the disk could provide around one and a quarter minutes of material. The system was marketed as the Urban Spirograph by Charles Urban, and discs were produced - but it soon disappeared

John Logie Baird, created the Phonovision system in the early 1930s, which mechanically produced about four frames per second. The system was not successful.
