<p>PURPOSE:To provide a reproducing device capable of smoothly performing a frame synchronization. CONSTITUTION:By a drum 2, a head mounted thereon is rotationally scanned against a tape to output the reproducing signal. The each scanning of head and tracking signals are fixed to a prescribed corresponding relation by a tracking control means 4, and the phase difference between the frame of reproducing signal and a reference frame is detected by a frame phase difference detecting means 5. The tracking signal-frame phase are decided from the value of frame phase difference by a phase correcting means 6 to make an optimum frame phase correction, then the reference frame and reproducing frame are synchronized. Since the correction is made by an optimum bus so that the corresponding relation for the head scanning-tracking signal is maintained even after the frame phase is corrected, the frame synchronization can be completed in a short time.</p> |
