Abstract: Embodiments of the invention include systems and methods for selective gripping and/or releasing of media cartridges using a robotic ratcheting gripper mechanism. Embodiments operate in context of a data storage library having a number of media cartridges physically located within slots of one or more magazines. A robot with a hand assembly uses a gripper mechanism to retrieve and ferry the cartridges between the magazines and one or more media drives. A novel gripper mechanism is provided that toggles between open and closed states according to movement of the gripper. In some embodiments, movement of a carriage from a retracted to an extended position extends the gripper mechanism and toggles its state, while movement of the carriage from the extended to the retracted position retracts the gripper mechanism while maintaining its state. Certain embodiments implement this functionality with simple mechanical components.

Abstract: A system prevents an excessive force from being applied to a handle of a tape drive. The system provides a base coupled to the handle of the tape drive. A lever assembly engages the base to move the handle when a force equal to the force required to move the handle is applied to the lever assembly. The lever assembly disengages the base when a force in excess of the required force is applied to the lever assembly and the force is not applied to the handle.

Abstract: The pass thru mechanism for automated cartridge library systems serves to interconnect two juxtaposed operationally independent automated cartridge library systems and provides a simple apparatus that makes use of gravity to obviate the need for complex mechanical mechanisms to pass the media cartridge between the juxtaposed automated cartridge library systems. In particular, the pass thru mechanism comprises a media cartridge receiver that accepts a media cartridge from an automated cartridge library robot and then deposits the media cartridge in a media cartridge positioning mechanism. The media cartridge positioning mechanism uses gravity to tumble the media cartridge down a ramp into a media cartridge transport that delivers the media cartridge to the robot located in the juxtaposed media cartridge receiving automated cartridge library system.
