Abstract
An information processing apparatus includes a hard disk drive, an acceleration sensor, and a determination section. The hard disk drive is capable of moving a head of the hard disk drive to a data-free landing zone. The acceleration sensor detects acceleration. The determination section obtains a low frequency component from the detected acceleration and determines whether it is necessary to move the head of the hard disk drive to the data-free landing zone based on the low frequency component.
