Abstract
In a disk drive in which a head disk assembly includes a slider suspension member and a parking ramp on which the suspension member rests when the disk drive is not operating, stiction forces between the suspension member and the parking ramp are overcome by applying simultaneously to the suspension member a dither in the form of rocking micromotion, and a bias force to move the suspension member at a low velocity required for loading a slider onto a disk without damage to the slider/disk interface.
