<p>PURPOSE:To quicken the restart of recording operation without disturbing a joint by transferring a tape by a prescribed amount in a forward direction after the tape is transferred by the prescribed amount in a backward direction in a temporary stop mode at a consecutive recording time and stopping the tape in a position locking the phase of a capstan motor in the shortest time. CONSTITUTION:The capstan motor is stopped in the case of moving from a recording mode I to a temporary stop state. A motor is reversed and the magnetic tape is transferred in a backward direction (unwinding II). At this time, the tape is transferred by the prescribed amount by counting a capstan FG signal. The motor is stopped temporarily again, and the tape is transferred by the prescribed amount in a forward direction (forward winding III). The amount is measured by counting the capstan FG signal. The tape 100 is fed frame by several frames in a forward direction. At this time, the tape position where a regenerative phase matching time is made minimum is selected. When the temporary stop state of the tape 100 is released, the motor 12 is rotated forward, and the rotation phase control of the motor 12 is performed by making a regenerative control signal obtained by running the tape 100 a feedback signal (regenerative phase matching V).</p> |
