Abstract
An acceleration sensing device senses the acceleration of a computer such that the computer is subject to zero support force (i.e., is in a free fall), and a control microprocessor of the disk drive unit determines that such state lasts for longer than a certain minimum of time. Upon these conditions being met, the control microprocessor signals the removal of the heads from the disk to park the heads.
