摘要:
A head retracting apparatus retracts a head on a storage medium upon detecting a fall. A counter-value calculating unit calculates a counter value that changes with an increase of a falling time and an increase of a non-falling time. A retraction determining unit determines whether to retract the head, based on the calculated counter value.
