Abstract
A disk drive uses the integration of the instantaneous velocities of the heads to estimate the distance the heads travel while latched. The disk drive can then determine if the heads are properly parked based solely on the distance traveled, thus avoiding the use of costly sensors. In the event that the heads cannot be properly parked due to some malfunction, the disk drive may store a special code in a nonvolatile memory. The special code directs the controller not to spin up or attempt to load the heads on any disk, preventing the disk from being damaged by the heads.
