<p>PURPOSE:To provide a reproducing device suitable to circuit integration and capable of executing frame synchronism smoothly. CONSTITUTION:A drum 2 outputs a reproduced signal by a mounted head rotation-scans a tape 1. A tracking control means 4 controls tape running so that respective heads traces the track of the tape 1. A frame detecting means 5 detects the track number information of the reproduced signal and outputs a reproduced frame signal having a pulse width in accordance with the even/odd of the frame. A frame phase correcting means 6 detects the phase difference between the reference and the reproduced frame signals and makes the tracking control means adjust the running in accordance with the detected value then the reference frame and the reproduced frame are synchronized. The number of wiring in the means required by the frame phase correcting is kept small. Since the frame phase difference is detected and corrected, the frame synchronism is completed in a short time.</p> |
