Abstract
A method for operating a disk drive apparatus in the Idle Mode reduces power consumption while meeting non-operating shock and vibration specifications. This is achieved by operating the disk drive apparatus with the head in the loaded state with the disk rotating at a first rotational speed, unloading the head, and in Idle Mode, rotating the disk at a second rotational speed lower than the first rotational speed, with the electronics depowered.
