Abstract: A system for selectively disallowing unwinding of a storage library robotic mechanism cable assembly in a direction that would otherwise allow a platform of the robotic mechanism to move downwardly via the force of gravity while at the same time allowing for winding up of the cable assembly and the platform, such as during shipping, manual access, replacement of the robotic mechanism, and/or the like. The system may include a ratchet pawl for engaging between adjacent teeth of a drive assembly of the robotic mechanism and an actuator for selectively moving or allowing for movement of the ratchet pawl into and out of the engaged position. In one embodiment, the system may include an electric switch or the like to sense when the pawl is engaged with the drive assembly.

Abstract: A cooling system for cooling computer component with a liquid provided at atmospheric pressure, or low pressure, that flows through channel defined in the computer component. The liquid is pumped from a reservoir to a discharge port, or weir, that is located above the computer component. The liquid flows through an in-feed manifold to diverters that direct the liquid into in-feed tanks located above a row of the computer component. The liquid flows through the channels and flow control orifices to a drain that returns the liquid to the reservoir.

Abstract: An expandable storage library for storing digital storage media, such as storage tapes or disks is provided. The library includes a base unit and robotic system to which additional expansion units may be added. Several expansion units may be installed in the library with the base unit so that the robotic system can access media storage racks in any of the expansion units or in the base unit. Doors on the base unit and expansion unit may be interlocked together to function as a single door. A Z pole guide on the base unit may be extended by adding expansion guide poles that guide the movement of the robotic system through the library.

Abstract: A data storage cartridge is positioned in a disk drive. The cartridge is positioned in the X and Y dimensions by contact between an alignment opening in the cartridge and an XY alignment pin in the disk drive and in the theta (rotational) dimension by contact between an edge of the cartridge and a theta datum in the disk drive. The cartridge is positioned in the Z dimension by contact between the cartridge and at least three Z datums.

Abstract: A disk drive includes a housing, a cartridge tray, and a cam plate. The cartridge tray is adapted to hold a cartridge that includes a data storage disk. The housing has a pair of vertical cartridge tray pin slots which hold tray pins that are part of the cartridge tray. The cam plate includes a pair of cam slots formed at an oblique angle to the cartridge tray pin slots. The tray pins extend through the cam slots into the cartridge tray pin slots. Movement of the cam plate back and forth causes the tray pins and cartridge tray to move vertically between a loaded position, where data can be read from or written to the data storage disk, to an unloaded position. The use of two cartridge tray pins allows the cartridge tray to rotate about an axis defined by the tray pins, and this action assists in locating the cartridge precisely in a repeatable position, in contact with a plurality of datums, when it is fully loaded.

Abstract: The robotic docking apparatus for a cartridge library system having a cartridge Storage array provides a docking apparatus on the robotic arm that mates with corresponding features on the storage compartments. The docking apparatus enables the cartridge retrieval mechanism to automatically and precisely align with the storage compartment that contains the selected data cartridge by using passive alignment mechanisms and without requiring the use of a vision system or expensive tight mechanical tolerances. The robotic docking apparatus is incorporated into the robotic arm in the form of a docking feature that protrudes from the front of the cartridge retrieval mechanism. The docking feature is of length sufficient to begin engagement of the mating docking receptacle formed in each of the storage compartments in the storage array prior to the remainder of the cartridge retrieval mechanism contacting the data cartridge stored therein.

Abstract: The present invention is related to a method and apparatus for limiting movement of an actuator assembly in a data storage/retrieval system. In one embodiment of the apparatus, a base is provided on which first and second devices are mounted. The first device is rotatably mounted to the base and reads or writes data to a data storage disk. The second device operates between first and second states. In the first state, the first device is capable of movement with respect to the base. In the second state, the second device operates to inhibit movement of the first device with respect to the base. The second device may operate in the first state when the first device is reading or writing data to the data storage disk, and the second device may operate in the second state when the first device is not reading or writing data to the data storage disk. In one embodiment, second device is rotatably mounted to the base between first and second positions.

Abstract: Disclosed is an apparatus that includes a base, a first device and a second device. The first device is configured to read or write data to a data storage disk. The first device is rotatably mounted to the base and configured to rotate in a first plane. The second device is also mounted to the base. The second device is configured to adjustably limit rotational movement of the first device in the first plane. In one embodiment, the second device includes a camming surface. The camming surface can be perpendicular to the first plane in which the first device rotates. In this embodiment, the second device is rotatably mounted to the base with the second device capable of rotation between first and second positions. The first device is rotatable between third and fourth positions when the second device is in the first position, and the first device is rotatable between third and fifth positions when the second device is in the second position. The fourth and fifth positions are different from each other.

Abstract: Disclosed is an apparatus such as a disk drive that includes a base, a first device, and a second device. The first device can read or write data to a data storage disk. The first device is movably mounted to the base. For example, the first device can move in orthogonal first and second planes. The second device is mounted to the base and is configured to limit movement of the first device in the second plane. In one embodiment, the first device is rotatably mounted to the base and includes first and second portions. The first portion is rotatably mounted to the base, and the second portion is rotatably connected to the first portion. In this embodiment, the first portion rotates in the first plane, and the second portion rotates in the second plane. The second device is configured to limit rotation of the second portion in the second plane. Rotation of the second portion is limited when the second portion engages the second device.

Abstract: A disk drive contains a pair of spring elements which act as eject limiters, engaging catches on a cartridge to prevent the cartridge from being completely ejected from the drive. The cartridge contains a data storage disk which could be damaged if, for example, the cartridge were to fall to the floor. After the cartridge has been retained by the eject limiters, the user may manually withdraw the cartridge from the disk drive.
