PCM AUDIO SIGNAL REPRODUCING APPARATUS ABSTRACT OF THE DISCLOSURE In an apparatus for reproducing either a video signal or a PCM (pulse code modulated) audio signal from a record medium, the existence of a PCM audio signal recorded on the record medium is detected in response to an identifying pilot signal recorded together with the PCM audio signal, and, when a video signal is being reproduced, detection of a PCM audio signal is obviated. Thus, even if the identifying pilot signal and a portion of the video signal are superposed upon each other on a frequency axis, erroneous assumption of the presence of a recorded PCM audio signal can be avoided to prevent incorrect reproducing operation.
