<p>PURPOSE:To stop a recording medium at an accurate position without providing any track for a control signal by generating a gate pulse with an on-track signal and a playback head position signal, and moving the recording medium, bit by bit, during a gate pulse period with a driving pulse. CONSTITUTION:A playback tracking error voltage is compared with a reference voltage by a comparator 26; and the on-track signal passed through the differentiating circuit composed of a capacitor C1 and a resistance R5 is supplied to a clock terminal and a position of a tape as the recording medium on the basis of a signal which is sent from a terminal 22 by the monostable multivibrator composed of a D type FF32, monostable multivibrator, and D type FF33 ad synchronized with the rotation of the head is supplied to a reset terminal, so that a D type FF25 generates a necessary gate pulse. An AND gate 36 applied with a high-level still picture specifying signal is opened during the gate pulse period to output driving-7 pulse from a D type FF34 successively. Then, the tape is moved, bit by bit, and stopped at a position for still-picture reproduction without providing any tracks for control signals.</p> |
