ABSTRACT:
A video tape recorder performs tracking by moving its video heads vertically with respect to the scanning direction of the video tracks through the use of an electric-mechanical transducer. The video tape recorder measures the cycles of the synchronizing signals included in the reproduced video signals, so that the electric-mechanical transducer shifts the video heads to enable regular measuring, thereby allowing the video heads to scan on the regular video tracks.
