Abstract
A method of operating a disk drive. The disk drive includes a disk having a disk surface, a slider disposable adjacent the disk surface, and a slider loading/unloading ramp for the slider. The method includes rotating the disk at a loading speed. The method further includes loading the slider from the loading/unloading ramp at a loading fly height above the disk surface. The method further includes rotating the disk at an operational speed greater than the loading speed. The method further includes operating the slider at an operational fly height above the disk surface less than the loading fly height above the disk surface. The method further includes rotating the disk at an unloading speed less than the operational speed. The method further includes unloading the slider from the disk to the loading/unloading ramp at an unloading fly height greater than the operational fly height.
