ABSTRACT:
An aerodynamic actuator latch for a disk file uses a fringe field from permanent magnets of the actuator assembly to generate a reverse bias torque, in lieu of a separate return spring. The latching mechanism includes a stop arm portion which cooperates with an actuator arm portion to ensure that the head of a disk file locked in a landing zone when the storage disk is not rotating. The reverse bias torque is preferably provided to the actuator mechanism via cooperation of a ferromagnetic slug within the stop arm portion and the fringe field of the actuator magnets.
