Abstract
A disk drive comprises a disk drive base, an actuator rotatably coupled to the disk drive base, a magnet disposed adjacent the actuator, and a latch. The latch is coupled to the disk drive base. The latch includes a latch body, a retention bore, a seating cavity, and a biasing ball. The retention bore extends into the latch body along a bore longitudinal axis. The retention bore includes a ball entrance defining a ball entrance diameter. The seating cavity extends from within the retention bore into the latch body. The seating cavity has an interior dimension perpendicular to the bore longitudinal axis greater than the ball entrance diameter. The biasing ball is disposed at least partially in the retention bore and at least partially within the seating cavity. The biasing ball comprises a magnetic material and has a ball diameter greater than the ball entrance diameter.
