 and Decca Records. The name Teldec is the result of taking the first three letters of both labels: Telefunken and Decca. Records manufactured by Teldec mostly were released under the Telefunken or Decca label, but normally these records contained no hint that they were made by Teldec. In 1983 Telefunken and Decca rectracted from their engagement in vinyl record production and Teldec was sold to Time Warner. In 1997 the remaining compact-disc production facility in Nortorf was to be closed by Time Warner, but a management buyout was done and the new founded company OK-media is continuing the CD production until now. In 2001, after the merger of AOL & Time Warner, Teldec closed down.

-encoded A/V-signal from thousands of concentric grooves, vertically recorded into the surface of a very thin, flexible vinyl disc. The disc was freely rotating on a thin cushion of air between the disc and a fixed plate at 1500rpm (25Hz), the disc being stabilized only by centrifugal force. The sampling frequency of the combined audio/video signal was about 2.7MHz. Maximum video playing time was 10 minutes on a 210 mm disc, amounting to about 15,000 concentric grooves on the disc, each storing two half-frame PAL-video-lines.
