Abstract
A disk drive comprises a disk, an actuator arm, a head attached to the actuator arm, a voice coil motor, a parking latch for latching the actuator arm in a latched position in order to park the head during a non-operating mode, a post, and an inertial latch for maintaining the actuator arm in the latched position when the disk drive is subjected to a physical shock. The inertial latch comprises a body having a protruding arm and a pivot surface, wherein during the physical shock the body rotates about the pivot surface such that the protruding arm engages the actuator arm. The body of the inertial latch further comprises a strip-spring comprising a first end inserted into a first receptor and a second end inserted into a second receptor such that the strip spring has an initial arc displacement when installed into the body of the inertial latch.
