Abstract
PURPOSE: To vary the amplification factor of the driving amplifier in accordance with the address difference signal or the target speed voltage by increasing the amplification factor when the target speed voltage is high and decreasing the amplification factor when the target voltage is low respectively.
CONSTITUTION: Driver unit 9 consists of target speed signal generator 4 which generates the target speed signals according to the address difference signal between the designated address and the present address, speed detector 5 which detects the motion speed of the head and converts it into the motion speed signal, and driving amplifier 6 which compares the target speed signal with the motion speed signal and then generates the driving signal to drive the head positioning mechanism in case some difference exists between the both signals mentioned above. Then the amplification factor of amplifier 6 is set to be expressed in the form of the function of the address difference signal or the target speed signal so that the amplification factor may be increased or decreased when the address difference signal or the target speed signal is large or small respectively. As a result, the performance of unit 9 can be exhibited satisfactorily, preventing the runaway of the head.
