ABSTRACT:
An apparatus for recording and reproducing a digital video signal on and from a common recording medium by using the head configuration common to the conventional one while maintaining exchangeability with the current analog VTR. An analog video and audio signals are recorded and reproduced on and from an video track and an underlying deep-layer track, respectively, by means of magnetic heads and magnetic heads. On the other hand, a digital video and audio signal is recorded and reproduced on and from two adjacent tracks by means of the magnetic heads for analog audio recording. During reproduction, an identification signal generating circuit generates an identification signal for discriminating a recorded signal, and a control signal is PWM modulated with the identification signal and recorded on a control track by means of a magnetic head.
