Patent ID: 8159788

Claim:
In a hard disk drive (HDD) having a base, a swing arm supported on the base so as to be rotatable in opposite directions about an axis of rotation, and a magnetic head supported by the swing arm, an actuator latch system comprising: a member integral with the swing arm and defining a notch at a rear end portion of the swing arm; and a latch lever disposed adjacent the rear end portion of the swing arm when the swing arm is in a position at which the magnetic head is parked, the latch lever having an arm portion mounted to the base so as to be rotatable about an axis of rotation, and first and second hooks at one end of the arm portion, each of the hooks being generally triangularly shaped with one of its corners forming a tip end projecting away from the arm portion substantially in one of the opposite directions in which the swing arm is rotatable, and the notch including a bight opening outwardly in substantially the other of the opposite directions, whereby the hooks selectively extend within the bight to engage said notch when the HDD experiences shocks while the magnetic head is parked, to thereby retain the swing arm in a position at which the magnetic head remains parked.
