Abstract
A crash stop is used for an actuator arm of a hard disk drive. The crash stop includes a base portion that is pivotally connected to a post that separates the magnets of a voice coil motor. Extending from the base portion is a tab portion that can be rotated between a first position and a second position. When in the second position the tab limits the movement of the actuator arm so that the sliders of the disk drive cannot move off of the disks. The actuator arm, voice coil motor and crash stop can be installed by initially placing the crash stop in the first position and orienting the actuator arm in an off disk position. The actuator arm and voice coil motor are then mounted to a base plate of the disk drive. The actuator arm is rotated to load the magnetic heads onto the disks of the disk drive. The crash stop is then rotated to the second position and a cover is subsequently attached to the base plate to enclose the assembly.
