ABSTRACT:
A magnetic recording disk drive includes a bidirectional rotary inertial lock to reliably lock the actuator in the parked position. The lock engages the actuator even in the presence of a rotational acceleration tending to drive the actuator into its crash stop. In one embodiment, the rotary inertial lock includes an arm being maintained at a neutral position in the absence of an external force and being freely rotatable in first and second opposite directions to lock the actuator and prevent its movement from or into a crash stop.
