Abstract
A crash stop for use in a rotary disc file storage system, particularly for use with a rotary-type electromechanical actuator, the crash stop comprising a dual stop mechanism for delimiting the travel of an actuator arm in either of two reciprocal directions, the stop having two symetrically oriented plain levers having separate spaced pivots, the levers each having first segments projecting from the pivot and adjustably spaced on either side of a stop pin fixed on the actuator arm and second segments oppositely projecting from the pivot and interconnected by a spring loaded, adjustment mechanism, whereby movement of the actuator arm is restricted by contact of the stop pin with one of the first lever segments and limited compression of a spring in the adjustment mechanism.
Claims10
In a disc file having an accessing mechanism including an actuator having a reciprocal movable member with connected recording heads for accessing the surface of a magnetic disc, a crash stop for restraining the reciprocal displacement of the moving member of the actuator comprising:
- a contact element mounted on the movable member of the actuator and movable in a generally reciprocal course with the movable member;
- contact means having first and second opposed contact faces;
- pivot means mounted to a stationary structure in said disc file for pivotally mounting said contact means to said structure with said contact faces positioned on the course of said contact element displaced from opposite sides of said contact element;
- and,
- bias means attached to said contact means co-acting with said contact faces for restraining displacement of said contact faces, whereby displacement of the actuator moving member may be restrained.
