Patent number: 10658001Abstract: One embodiment provides a system comprising a motor and a disc selector mechanism. The disc selector mechanism is coupled to a bottom of a guide cage and maintained in a space below the cage. The disc selector mechanism comprises a shaft, transmission components, and a slide assembly that is laterally slidable along the shaft in response to the motor driving the transmission components. The slide assembly comprises a slide coupled to the shaft, a pivot bar coupled to the slide, and pick blades pivotally coupled to the pivot bar. A linear motion of the slide assembly along the shaft drives a linear translation of the pivot bar. The linear translation drives a pick blade of the slide assembly to move towards a side of the cage and out of the space and to pivot to a raised position to contact and lift a disc upwards into a disc gripper device.Type: GrantFiled: September 30, 2019Date of Patent: May 19, 2020Assignee: International Business Machines CorporationInventors: David J. Altknecht, John S. Best, Donald S. Bethune, William M. Dyer

Patent number: 10600441Abstract: An apparatus includes a motor configured to drive a driving element within a housing. A pivoting element on a shaft is connected to the housing. The pivoting element is connected to a moveable jaw device and configured to force the moveable jaw device at any given moment towards or away from a face of a storage disc, as the pivoting element pivots about a first axis. A fixed jaw device is connected to the housing. The moveable jaw device and the fixed jaw device form a gripper device configured to clamp a particular portion of opposite first and second surfaces of a storage disc.Type: GrantFiled: December 7, 2018Date of Patent: March 24, 2020Assignee: International Business Machines CorporationInventors: David J. Altknecht, Donald S. Bethune, William M. Dyer

Patent number: 10580451Abstract: A disc cassette includes a curved portion. The curved portion includes multiple ribs that define multiple disc slots. The disc slots are configured to hold multiple discs that are spaced apart by the ribs. The disc cassette further includes multiple index features positioned on an inside edge of the curved portion. The index features are configured to allow alignment of a kicker device of a disc retrieval unit (DRU) to a disc of the disc cassette to lift the disc into a disc gripper device without disturbing one or more other discs of the disc cassette that are adjacent to the disc.Type: GrantFiled: June 28, 2019Date of Patent: March 3, 2020Assignee: International Business Machines CorporationInventors: David J. Altknecht, Donald S. Bethune, William M. Dyer, A. David Erpelding, Steven R. Hetzler, Drew B. Lawson, Daniel F. Smith
