ABSTRACT:
A voice coil motor control technique which can improve the reliability of a hard disk drive by decentralizing the abrasion of a parking zone of a disk used as a magnetic recording medium includes: when power is first supplied to the hard disk drive having a head positioned in a first region within the parking zone, driving a spindle motor in order to rotate the disk and supplying a fixed current to a voice coil motor in order to move the head positioned in the first region therewithin; applying to the voice coil motor, a fixed current in a reverse direction so as to move the head to a second region within the parking zone; and supplying a unlatching current to the voice coil motor in order to move the head to a data zone when a uniform velocity rotation of the spindle motor is sensed.
