20090059433 | ACTUATOR LATCH SYSTEM OF HARD DISK DRIVE - An actuator latch system of a hard disk drive keeps an actuator of the hard disk drive in place in a state in which a read/write head mounted to a swing arm of the actuator is parked. The latch system has first and second protrusions at upper and lower parts of a rear end portion of the swing arm, and a latch lever having first and second hooks at upper and lower parts of a leading end of the lever. The latch lever, like the actuator, is mounted to a base of the hard disk drive so as to be rotatable about a respective axis. The first hook engages the first protrusion of the swing arm when the arm is inadvertently rotated in a first direction to arrest such inadvertent rotation, and the second hook engages the second protrusion of the swing arm when the arm rotates for a second time in the first direction due to rebounding that occurs in the latch system after the first protrusion and the first hook collide. | 03-05-2009 |
