Abstract
A movable load/unload parking apparatus for a disc drive has an elongated parking member pivotally supported adjacent a data storage disc or stack of discs in the drive. The parking member is operable to move between a first position during drive shutdown and a second position during drive operation. In the first position, a pickup portion of the parking member extends over a peripheral portion of the disc to receive and carry the transducer or transducers beyond the outer diameter of the disc when the actuator rotates the actuator arm outward to a park position. At the same time a crash stop portion of the parking member is repositioned away from the actuator arm to permit the outward rotation. In the second position, the pickup portion of the parking member is positioned beyond the outer diameter of the disc and the crash stop portion is positioned to prevent movement of the actuator arm beyond the outer diameter of the disc.
