Abstract

The invention relates to a method and an apparatus for controlling the drive of a head disc, in which not only noises but also the power consumption during the seeking period is reduced. The invention also provide a personal computer which can reduce noises due to the resonance occurring with the apparatus for controlling the drive of a hard disc during the seek period. According to the invention, each time seryo information is detected by a detecting means, a calculating and determining means determines whether the moving speed of the head is within a predetermined range including a target speed or not, during a period from a point at which the moving speed of the head reaches the target speed to a predetermined point at which a deceleration of the head starts. If the determination is YES, a current supplied to a voice coil motor for driving the head is turned off by a motor driver. If it is NO, a current is supplied to the voice coil motor by the motor driver.
