Abstract
A disk drive having an actuator-activated pumping mechanism is disclosed. The pumping mechanism creates a low pressure operating environment for the disk drive in order to enhance the performance of the drive at higher rotational operating speeds. Through the use of an engaging element, the actuator motor acts to drive a pumping element. This design does not use a separate electrical motor to evacuate the disk drive housing. Instead, the natural motion of the actuator provides the necessary power to drive the pumping element.
