Third time lucky?

摘要

In 1982, right at the end of the golden age of vinyl, Teldec (jointly owned by Telefunken and Decca) experimented with a completely different way of cutting hi-fi LPs, called Direct Metal Mastering. This had spun off from the work done by Teldec, at a semi-secret lab in Finchley run by Decca's respected recording engineer Tony Griffiths, on TeD - a floppy video disc. The TeD video disc had a superfine hill-and-dale groove cut in a flimsy plastic disc about the size of an EP. The disc span at 1500rpm and played ten minutes of colour video when tracked by a mechanical sled-shaped stylus.
