ABSTRACT:
Apparatus for recording audio and video signals comprises a signal processor for producing a processed video signal and a frequency-modulated audio signal. The frequency-modulated audio signal is obtained by frequency-modulating a carrier in response to an input audio signal. A magnetic recorder records both the frequency-modulated audio signal and the processed video signal in oblique tracks arranged successively on a magnetic tape. The recording is done selectively in a first recording mode wherein the oblique tracks are formed with spaces between successive tracks or a second recording mode wherein successive tracks are contiguous. A modulation control controls the frequency-modulation carried out by the signal processor to produce the frequency-modulated audio signal with a first modulation index in the first recording mode and with a second modulation index greater than the first modulation index in the second recording mode.
