ABSTRACT:
A falling-time measuring unit measures time for which a fall of a storage device is consecutively detected by a fall detecting sensor. A head-position detecting unit detects a position of the head on a storage medium at a time of starting measuring the time. A moving-time calculating unit calculates necessary time for moving the head from the detected position to a destination position. A first-threshold determining unit determines whether the measured time exceeds a threshold calculated by a threshold calculating unit. A head-movement processing unit moves the head to the destination position when it is determined that the measured time exceeds the first threshold.
