Title: Movable load ramps and crash stop for a disc drive

Abstract: A movable load/unload parking apparatus for a disc drive has an elongatedparking member pivotally supported adjacent a data storage disc or stackof discs in the drive. The parking member is operable to move between afirst position during drive shutdown and a second position during driveoperation. In the first position, a pickup portion of the parking memberextends over a peripheral portion of the disc to receive and carry thetransducer or transducers beyond the outer diameter of the disc when theactuator rotates the actuator arm outward to a park position. At the sametime a crash stop portion of the parking member is repositioned away fromthe actuator arm to permit the outward rotation. In the second position,the pickup portion of the parking member is positioned beyond the outerdiameter of the disc and the crash stop portion is positioned to preventmovement of the actuator arm beyond the outer diameter of the disc.
