ABSTRACT:
A limit stop assembly for use with a linear actuator in a sealed magnetic disc drive which establishes inner and outer limits of travel and provides shock absorption for the pickup heads and carriage at the limits of travel. The assembly is mounted on an adjustable seat in a wall of the actuator. A first stop member is threadably attached to the seat, a second stop member is positioned about the first member, and a spring yieldably biases the second stop member away from the stop surface of the first member. A cup shaped member is positioned about the stop surface of the first member and is yieldably biased by the spring. The first stop member extends through a hole in the second stop member, and a shoulder of the first member limits the travel of the second stop member. Adjustment of the stop positions is accomplished by movement of the seat and the first member within the seat.
