Television Electronic Disc (TeD) is a discontinued video recording format, released in 1975 by Telefunken and Teldec. The format used 8-inch-diameter (200 mm) flexible foil discs, which spun at 1,500 rpm on a cushion of air. TeD never gained wide acceptance, and could not compete against the emerging videocassette systems of the time.[1]
