Abstract
PURPOSE:To stop a head to a correct position of an object track in a short period by calculating a real value representing the present position of the head based on the result of count of stroke pulses and applying position control of the head based on the actual value. CONSTITUTION:A position signal generating circuit 12 receives a position signal from an encoder 11 to give a position signal PS, a stroke pulse generating pulse circuit 20 receives the signal to generate a stroke pulse TP. A counter 32 receives a direction signal D from the circuit 20 and the stroke pulse TP to count. A software section 33 of an actual value calculation means 30 receives a count C from the counter 32, a code S and a signal (x) with a sign of the position signal from the ADC 31 to calculate the actual value xa of the head position to give it to a software section 41 of an actuator drive control means 40. The software section 41 compares the value xa with an object value (e.g., 0) and gives a drive signal DS to a drive circuit 5 of the actuator 4 via a DAC 42 so as to eliminate the difference.
