Abstract
A retention and retraction device for a slider and suspension in a magnetic disk drive. A cam actuation device is placed at the outer periphery of each disk in a disk drive having a multi-disk stack. A cam surface attached to a load beam that is part of the suspension engages the finger when the actuator arm is rotated far enough toward the outer periphery. The finger displaces the cam and attached suspension. In turn, a slider attached to the suspension is moved away from a disk surface over which it had been engaged in a flying relationship.
