ABSTRACT:
A magnetic head parking apparatus of a hard disk drive for parking a magnetic head installed on an actuator includes a deformation member reversibly deformable in a direction in which the magnetic head is separated from a disk by pressing one side of the actuator, and a deformation control unit controlling deformation of the deformation member such that during parking the magnetic head, the deformation member is deformed in the direction in which the magnetic head is separated from the disk. Thus, since the slider is parked in a state of being separated from the hard disk, damage to the magnetic head due to an impact can be reduced. Also, since an additional parking area is not needed to be made in the hard disk, more data space can be secured in the hard disk.
