ABSTRACT:
Tracking control apparatus and method for a digital/analog recording/playback system which is capable of recording and playing back a digital video signal as well as an analog video signal compatible with an existing VHS system. A tracking signal is recorded by first and second heads for the recording and playback of an analog video signal, and a digital video signal is recorded by third and fourth heads for the recording and playback of the digital video signal. The recorded tracking signal is played back by the first and second heads and the recorded digital video signal is played back by the third and fourth heads. The digital video signal is recorded on a portion of a tape wound at an angle of 180.degree. with respect to a head drum and the tracking signal is recorded on upper and lower 5.degree. portions adjoining the 180.degree.-wound portion of the tape. Therefore, a loss of the digital video signal can be avoided. This has the effect of obtaining a high picture quality.
