ABSTRACT OF THE DISCLOSURE A reproducing section of a helical scan VTR for reproducing a color television signal recorded in a plurality of successive parallel tracks on a magnetic tape and comprised of a video signal and at least one of a frequency-modulated audio signal and the combination of a PCM audio signal and run-in signal, with the video signal and frequency-modulated audio signal being recorded only in a main section of each track and the PCM audio signal being recorded only in an overscan section of each track, the VTR including a pair of magnetic heads which scan the tracks to reproduce the information signal recorded therein; a pair of switch circuits connected to the heads and which separate the information signal reproduced during scanning of the main section of each track and a signal reproduced during scanning of the overscan section of each track; a detector which detects the presence or absence of a run-in signal from the separated signal reproduced during scanning of the overscan section of each track and produces a detection signal in response thereto; an output; and a switch for switching an analog audio signal reproduced from the PCM audio signal to the output in response to the detection signal when a run-in signal is detected and an analog audio signal reproduced from the frequency-modulated audio signal to the output in response to the detection signal when no run-in signal is detected.
