Abstract: 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.

Abstract translation: 当驱动器进入空闲掉电模式时，硬盘驱动器（10）将驱动器的磁头（24）锁定离开盘（18）的数据扇区。 当磁盘驱动器（10）进入空闲掉电模式时，对音圈电机（40）的电力终止。 在向音圈电机（40）通电之前，磁头（24）被移动到盘（18）的不包含通常称为着陆区的数据的内径位置。 头部（24）通过捕获致动器臂的一部分的闩锁保持在着陆区域上。 闩锁完全固定致动器臂（28），使得冲击负载不会将磁头（24）移动到磁盘（18）的数据扇区上并损坏磁盘（18）。 当磁盘驱动器（10）离开空闲电源时，闩锁与致动器臂（28）脱离，音圈（36）上电，并且磁头（24）在数据扇区之后移回以备后续 磁盘访问。
