<p>A hard disk drive (10) that latches the heads (24) of the drive away from the data sectors of the disk (18) when the drive enters an idle power down mode. Power to the voice coil motor (40) is terminated when the disk drive (10) enters the idle power down mode. Before terminating power to the voice coil motor (40), the heads (24) are moved to an inner diameter location of the disk (18) which does not contain data, commonly referred to as a landing zone. The heads (24) are maintained on the landing zone by a latch that captures a portion of the actuator arm. The latch fully secures the actuator arm (28) so that a shock load will not move the heads (24) onto the data sectors of the disk (18) and damage the same. When the disk drive (10) exits the idle power down, the latch is disengaged from the actuator arm (28), the voice coil (36) is powered up, and the heads (24) are moved back over the data sectors for subsequent disk access.</p> |
