<P>PROBLEM TO BE SOLVED: To prevent crushing due to a fall by predicting a fall shock. <P>SOLUTION: The hard disk drive has an acceleration sensor inside and is provided with a mechanism which retracts a head on detecting a falling state. In detail, the hard disk drive is equipped with the acceleration sensor and a controller which performs control for retracting the head to a shipping zone when a speed exceeds a certain value, thereby retracting the head of the hard disk drive to the shipping zone before the hard disk drive has a shock due to a fall. <P>COPYRIGHT: (C)2003,JPO |
