<p>PURPOSE:To execute the miniaturization and to decrease a cost by controlling the rotation of a winding reel in accordance with the signal of the difference between a reproduced address and a reference address and correcting the change of the rotation due to the tape winding diameter of the winding reel based on the signal of the difference. CONSTITUTION:A reproducing signal is sent to a reproducing processing circuit 8, a prescribed signal is processed, supplied to a reproducing frame address detecting circuit 9 and a reproducing frame address PAD is extracted. The reproducing frame address PAD is supplied to a subtracting circuit 10, a reference frame address RAD from a reference frame address generator 11 is subtracted and a subtracting value N1 is obtained. By a third control signal S3 composed of a first control signal S1 in accordance with the subtracting value N1 and a second control signal S2 generated based on the subtracting value N1 to correct the change of the rotation due to the tape winding diameter of a winding reel 4, a tape speed is controlled by controlling the rotation of the winding reel 4. Thus, the miniaturization and the decrease in cost can be executed.</p> |
