Abstract
A flying on demand (FOD) voltage of a hard disk drive (HDD) is controlled by detecting a shock occurring to the HDD on which a magnetic head that records data on a disk or reproduces data from the disk is mounted, and if the shock is detected, controlling the FOD voltage that is applied to the magnetic head to thermally expand an end of the magnetic head.
