Abstract
PURPOSE:To enable a tape to travel at constant speed by controlling a reel rotational speed with a signal based on the difference between the arithmetic value at the time of moving a tape by a capstan motor and the arithmetic value at the time of moving the tape by a reel motor. CONSTITUTION:Based on a first prescribed frequency clock f1 at the time of traveling the tape by a capstan motor, the rotation period of reels 1 and 2 is counted. Based on respective counted values, a prescribed counting is executed by a counter 6, and a clock f1 is changed so as to stop an arithmetic value in a prescribed range. Further, at the time of moving the tape by the reel motor, the rotation period of reels 1 and 2 is counted based on a second prescribed frequency clock f2. Based on respective then counted values, the prescribed counting is executed and by the signal based on the difference between the arithmetic value at the time of moving the tape by the scanning motor and the arithmetic value at the time of moving the tape by the reel motor, the reel rotational speed is controlled.
