。 A digital VT in which a digital video signal and a digital audio signal are divided into blocks of predetermined samples, recorded on a magnetic tape by a rotating magnetic head so as to form an inclined track, and then reproduced.
In R, an address signal including at least a track number, a block number, and a time code is recorded for each predetermined block, and at the time of recording and reproduction, an address signal is recorded based on a reproduction signal of the address signal or a deviation detection signal of the rotating magnetic head. A digital VTR comprising a tracking error signal detection circuit for obtaining a tracking error signal of the rotating magnetic head.
