ABSTRACT:
A helical scanning type video tape recorder is provided with an audio signal recording/reproducing circuit in which the audio signal is submitted to frequency modulation, after which the modulated audio signal is recorded on a video track by a rotary video head while a video signal is also recorded on the same track. This provides very good quality of reproduction of the audio signal. In order to reduce crosstalk interference of audio signals between adjacent tracks, a dynamic range of the audio signal is compressed to have a predetermined characteristic in the recording process, and then expanded to compensate to the original dynamic range in the reproducing process.
