ることを特徴とするトラツキング制御装置。 A rotary head that scans the surface of a magnetic tape running in a predetermined direction in a direction crossing the running direction to read digital signals recorded on the magnetic tape and outputs a playback signal, and a rotary head that performs waveform shaping of the playback signal to generate playback data. an input processing section that outputs a synchronization clock from the reproduction data; a clock extraction section that extracts a synchronization clock from the reproduction data; and a clock extraction section that recognizes a parity signal included in the reproduction data in synchronization with the clock;
It consists of a signal processing section that outputs an error detection signal indicating that a detection error has occurred based on this parity signal, and an error pulse detection section that detects this error detection signal and outputs a tracking signal, and this tracking signal disappears. A tracking control device for adjusting the rotational speed of the magnetic tape feeding capstan motor.
