Abstract
PURPOSE: To expand a recording area without deteriorating positioning precision while obtaining a broad-band position signal, by generating an equivalent position signal from a few pieces of position information and the position signal of a speed detector.
CONSTITUTION: Position information write area 5 is reduced and head actuator 13 is fitted with speed detector 14. The gain of the speed signal of detector 14 is adjusted by coefficient unit 17 and the gain of the position signal of sample holding circuit 12, on the other hand, is also adjusted by coefficient unit 17 to equalize voltage levels of both the signals. Then, both the signals are added together by adder 18, whose output is input to primary delay circuit 19. Circuit 19, having its time constant T set equal to ratio Ax/Ay of position gain Ay of coefficient unit 17 to Ax of 16, integrate the high frequency component of the sum signal properly. Therefore, the circuit outputs an equivalent position signal consisting of the low frequency component of the position signal and a high frequency component obtained by integrating the speed signal. this signal is applied to actuator 13 by way of controller 20 and power amplifier 21 to move head 11 to a desired position.
