Apparatus for guiding and locking a rotary actuator

摘要

An apparatus to guide and lock a rotary actuator at a limiting rotational angle in a disk storage. A rotary actuator is attached within a housing so that it is rotatable on a pivot shaft. An iron piece is rotated integrally with the rotary actuator and is attracted in magnetic cooperation with a lock magnet. A retract magnet is attached to housing and assists in rotation of the actuator during an unload operation in which the rotary actuator is removed to a load/unload ramp.
