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 |
20090213500 | ACTUATOR LATCH SYSTEM OF HARD DISK DRIVE - An actuator latch system of a hard disk drive selectively locks in place and releases a rotatable swing arm having a front end portion supporting a magnetic head and a rear end portion on which a voice coil motor (VCM) coil is disposed.

The hook is received in the notch in the rear end potion of the swing arm to arrest rotation of the swing arm in a predetermined direction. The magnet of the latch lever faces a section of the VCM coil such that when the hard disk drive is started, the latch lever is rotated by a force generated due to current flowing through the section of the VCM coil faced by the magnet and the magnetic field generated by the magnet. The rotation of the latch lever prevents the hook form interfering with the rotation of the swing arm in the predetermined direction. | 08-27-2009 |
