Abstract

PURPOSE:To smoothen the readout of the next reproducing data by supplying an error voltage to impress a motor driver circuit when an RF signal disappears during the search servo operation by holding the voltage just prior to disappearing the RF signal. CONSTITUTION:When a rotary drum 1 comes to a non-RF signal part of a tape T, a holding signal comes out of an RF detector 12, so as to hold the error voltage just prior to disappearing the RF signal into 1st and 2nd holding circuits 16 and 17. Then, this error voltage is supplied to the motor driver circuit 14, so as to rotate a drum motor 8 by the drive voltage just prior to disappearing the RF signal. And, in case of extremely fluctuating the rotary drum 1 in the speed of revolution due to a long period of the non-RF signal, the revolution is checked by an FG cycle measuring instrument 10 to bring it within a prescribed range. By this method, the readout of the next reproducing data is smoothened even when the RF signal disappears during the search servo operation.
