ABSTRACT:
Apparatus for recording and reproducing an information signal comprising at least an analog audio signal in a plurality of successive tracks on a magnetic tape includes a PCM processing circuit for converting an analog audio signal into a PCM audio signal; a video signal processing circuit for processing a video signal to produce an output video signal; a rotary magnetic head assembly for recording the output video signal and the PCM audio signal in the plurality of successive tracks on the tape; a switch assembly for supplying the output video signal and the PCM audio signal to the rotary magnetic head assembly; and a control circuit for controlling the switch assembly to supply the output video signal and the PCM audio signal to the rotary magnetic head assembly during a video use mode so that the latter records the output video signal in a main section of each track and to supply only the PCM audio signal to the rotary magnetic head assembly during an audio use mode so that the latter records the PCM audio signal in different segments of the main section and overscan section of each track.
