Abstract
A disk drive includes a housing including a support post extending from the housing. The support post defines a post axis. The disk drive further includes an actuator rotatably coupled to the housing. The disk drive further includes a VCM top plate physically coupled to the housing and comprising a ferromagnetic metal. The disk drive further includes a VCM magnet magnetically coupled to the VCM top plate. The disk drive further includes an actuator latch contactable with the actuator. The latch includes a post opening. The latch is pivotably mounted about the support post with the support post disposed in the post opening. The disk drive further includes a pivot ball disposed in the post opening and partially protruding from the latch between the VCM top plate and the latch along the post axis.
