A reset circuit asserts a reset signal when at least a power-off detection signal or a drop detection signal is asserted. When the reset signal is asserted, an emergency unload circuit supplies a voice coil motor with a current for retracting the head to the retract area. The emergency unload circuit uses an auxiliary power supply as an operation power supply thereof.
