  • Patent number: 6578257
    Abstract: A media rework tool for discs and/or a spindle motor carrying a disc pack is disclosed that has a slider plate mounted on a base for lateral movement between a retracted position and an extended position. The slider plate holds a spindle motor with a disc pack mounted on it, and moves between the two positions. The tool includes a gripper assembly having a plurality of opposing arms for grasping predetermined discs within a disc pack on the spindle motor when the slider plate is in the retracted position. The gripper assembly raises the predetermined discs and any intermediate spacer rings upward for temporary storage on a media guide to allow the remainder of the disc pack to be reworked, such as for replacement of a defective disc or spindle motor when the slider plate is laterally moved to the extended position. Following reworking of the remainder of the disc pack, the spindle motor is returned to its centered position relative to the media guide and the gripper assembly.

The gripper assembly raises the predetermined discs and any intermediate spacer rings upward for temporary storage on a media guide to allow the remainder of the disc pack to be reworked, such as for replacement of a defective disc or spindle motor. A method of reworking a disc pack includes centering the disc pack between opposing arms of a gripper assembly and beneath a cylindrical media guide. A plurality of the opposing arms close to grasp a predetermined number of discs, and the gripper assembly is raised to transfer the grasped discs, and any intermediate spacer rings, from the spindle motor to the media guide. Following reworking of the remainder of the disc pack, the spindle motor is returned to its centered position relative to the media guide and the gripper assembly.
