Abstract

PURPOSE:To prevent the occurrence of the disconnection of servo caused by the variation in DC component of a tracking error signal by separating a tracking error signal into a DC component and a tracking error signal component, amplifying the components with different amplification ratios, and inputting them in a mixing circuit. CONSTITUTION:The DC component of a tracking error signal ET flows only through a resistor R2 by the DC blocking capacitor of an amplification ration determining circuit 9, while tracking error signal component flows through both a resistor R1 and the resistor R2. Therefore, the amplification ratio is determined by the relation between the resistor R2 and a resistor R3, and thus the amplification ratio for the tracking error signal component is determined by the resistors R1-R3, and amplified by an amplification circuit 10. A speed servo circuit 8 generates a speed control signal SC so that the rotational speed of a tape feeding motor 7 is coincident with an instruction speed. The tracking error signal ET and the speed control signal SC are mixed with each other in a mixing circuit 5, and its 5 output is supplied to a driver 6 in order to control the rotational speed of the motor 7. As a result, the disconnection of servo caused by the variation in DC component can be prevented.
