ABSTRACT:
An apparatus for recording and reproducing a video signal and a digital audio signal, the audio signal being recorded and reproduced in either a first mode or a second mode, includes a rotary drum having a pair of rotary heads and records the video signal and selectively records the audio signal on a magnetic tape wrapped around the rotary drum. When the video signal and selected digital audio signals are reproduced, a detector detects the frequency of a predetermined portion of the reproduced signal and judges the mode of the digital audio signal on the basis of the detected frequency.
