Disk drive magnetic actuator latch mechanism

摘要

A disk drive magnetic actuator latch mechanism for use in hard disk drives. The present invention discloses a latch mechanism which includes a latch lever having a magnetic member attached to or moulded into each end of the lever. The lever is pivotally mounted about a pivot pin in the vcm assembly. The magnet member located on the latch lever tail is positioned between the vcm magnets when the mechanism is in the latched state. The unlatching force is provided by the presence of the magnetic member in the vcm gap, as the attraction of the member in the vcm field resists rotation of the latch lever. <IMAGE>
