ABSTRACT:
A head position signal Y(N), which represents the size and direction of the deviation of the current position of a magnetic head to the target position in terms of a digital value, is input at intervals of sampling cycle TS. A main control section 68 generates and outputs a motor current control signal U(N) representative of a control amount of motor current in terms of a digital value. The main control section 68 is provided with a digital filter 86 so that the head position signal Y(N) is input. The digital filter 86 has a gain which becomes a peak with respect to the component of a frequency in a narrow band including a predetermined angular frequency .omega..sub.o and which becomes almost 0 with respect to the frequency components other than the narrow band. The main control section 68 is further provided with a phase change section 88, which delays the phase of the signal output from the digital filter 86 by 5 TS and outputs it, so that the signal whose phase was delayed is added to the motor current control signal U(N) through a summing point 74.
