Television Electronic Disc
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]
History
Initially known as "The Video Disc" or the Teldec Television Disc, TeD (Television Electronic Disc) was first announced at a press conference in
Marketing
By autumn 1972, the name of the system had just been changed to TeD (for Television Disc) and the playing time of the eight-inch disc had been doubled to 10 minutes. TeD players were finally introduced on the West German market on 17 March 1975. Six labels offered programs: Decca, Teldec Intertel, Telefunken, Ufa/ATB, Ullstein AV and Videophon. Within the first three months 6,000 players had been shipped to 2,500 dealers, and 50,000 discs were in the shops. Sanyo Electric Co., Ltd. of Japan, which had been conducting similar research itself (but was by now also developing the V-Cord videocassette recorder), was granted a licence to produce a version that would play out in the NTSC television format and by the end of 1976 had devised a long-awaited auto-changer that took 12 10-minute discs. Also in Japan, General Corporation took a manufacturing licence in July 1976 with an expectation of coming to market in April 1977. A software consortium, Nippon Video Systems, was formed around the same time. By the end of 1978 Telefunken itself had adopted VHS.[2]
