    摘要: A sample-information extracting unit acquires a fall signal indicating whether a storage device is falling, conducts a sampling in response to the fall signal, and sequentially extracts sample information including either one of first information indicating a falling state and second information indicating a non-falling state. A retraction determining unit determines whether to retract the head, based on features of an array of the extracted sample information.

    摘要: 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.

    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.

    摘要: A fall sensor detects a fall of a storage device. A first moving unit moves the head to a predetermined position on a storage medium when a falling time exceeds a first threshold. A second moving unit retracts the head from the predetermined position to a ramp when the falling time exceeds a second threshold.
