Abstract
An information processing apparatus is disclosed. The information processing apparatus includes a hard disk drive, an acceleration sensor, a determination section, and a threshold value setup section. The hard disk drive is capable of retracting a head to a data-free landing zone. The acceleration sensor detects acceleration. The determination section obtains high frequency components from acceleration information detected by the acceleration sensor, obtains a vibration level corresponding to the obtained high frequency components, compares the vibration level with a threshold value which has been set up, and determines whether or not there is a necessity to retract the head of the hard disk drive to the data-free landing zone. The threshold value setup section allows a user to change the threshold value and set up the changed threshold value.
