Abstract

1319933 Recording and playback of television signals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 March 1972 [22 March 1971] 12586/72 Heading G5R The rotary head shaft 3 of a helical-scan video tape recorder carries a turntable 4 for supporting and driving a video-audio record foil disc 6 and drives a belt transmission 12 for moving a pick-up 13 over the disc 6. The output of the pick-up is applied through an additional equalizer stage to a video limiter stage, and an additional audio separating stage is provided, having its input connected at a point subsequent to the f.m. demodulator and its output connected to the input of the lowfrequency audio amplifier. Insertion of a cassette into the tape recorder switches the operative connections from the disc to the tape portions of the apparatus, and additional switches may be provided to enable signals from the disc 6 to be rerecorded on a tape.
