ABSTRACT:
An actuator latch system of an HDD retains a swing arm in place when the magnetic head of the HDD is parked and includes a rotatable latch lever having a hook that absorbs shock when engaging the swing arm. A rear end of the swing arm has a corner portion. The hook has first and second portions with a third portion extending there between Inner surfaces of the first through third portions delimit a slot. The inlet of the slot has a width less than the corner portion. The inner surface of the first portion of the hook contacts a first surface of the rear end of the swing arm, and the inner surface of the second portion of the hook contacts a second surface of the rear end of the swing arm, when a shock rotates the swing arm while the magnetic head is parked.
