Abstract
A voice coil actuator utilizes an eddy current magnet configured for positioning proximal to the outer perimeter side face of one or more recording disk, and which cooperates with the conductive side face to generate an eddy current force to rotate a latch lever to an unlatched position. Embodiments may include an end cam on a base on which the latch lever is rotatably disposed, and the latch lever includes a cam follower capable of rotatably engaging with the end cam, whereby the magnetic attraction between the eddy current magnet and the voice coil actuator yoke generates a latch bias force which causes the end cam and cam follower to engage or mesh in order to hold the latch lever in a latched position.
