Abstract: A cartridge magazine is shown for placement in a robotic media library. The magazine body has two walls to guide a tape cartridge into a final stopping position. A prong extends into the cartridge from a first wall and an opening is formed in the second wall to permit a friction pad to contact an opposing side of the cartridge. The friction pad is mounted onto a lever that rotates upon a pivot outside a cartridge chamber on the magazine body. The lever is pushed by a spring to ordinarily extend the friction pad well into vacant cartridge chambers. An operator pad of the lever may extend out of the magazine body for engagement by an operator or by door pressures to retract the friction pad so that the cartridge becomes either disengaged, or slightly engaged with the friction pad.

Abstract: An invention for use with transporting media cartridges between a first storage library and a second storage library. The invention comprises at least two pass through ports connecting the first and second storage libraries for use in transporting media cartridges between the first and second storage libraries. The at least two pass through ports provide redundant operation of the multiple data storage library system to ensure media cartridge transportability between the first and second storage libraries in the event that one of the at least two pass through ports should become inactive.

Abstract: A calibration apparatus for use with a storage system for storing a plurality of objects in an array of object storage locations. In a preferred embodiment, the calibration apparatus includes a target affixed in a predetermined location to the storage system, an object retrieval mechanism, and an imaging system. The object retrieval mechanism is used for retrieving objects from the object storage locations and has a principal direction of movement which is perpendicular to a plane in which an exposed surface of each of the plurality of objects lie. The imaging system is attached to the object retrieval mechanism for imaging the target. The imaging system is positioned such that the direction from the target to the imaging system is parallel to the principal direction.
