ABSTRACT:
The present invention includes a disc drive shocker having a fast valve which can be moved from a full on position to a full off position within a desired interval of time to impart a shock to a disc drive. The valve is connected to a valve actuator which moves the valve spool within the valve housing. The valve actuator is connected to the valve spool though a lever. The lever is pivotable about a fulcrum. The pivot point of the fulcrum is adjusted, away from center, such that the end of the lever connected to the valve spool moves more quickly than the end of the lever connected to the valve actuator.
