摘要:
A pass-through mechanism that couples a first linear tape library string to a second linear tape library string is maintained. A first robotic assembly associated with the first linear tape library string places a tape from the first linear tape library string into the pass-through mechanism. The pass-through mechanism moves the tape to a position where the tape can be removed by a second robotic assembly associated with the second linear tape library string. The second robotic assembly removes the tape from the pass-through mechanism and places the tape into the second linear tape library string.

A storage cartridge retention device employs a deep storage slot for storing one or more storage cartridge(s) through its front opening and biases the stored storage cartridge(s) in a direction of its front opening. The storage cartridge retention device further employs a retaining gate external to the deep storage slot and movable relative to the front opening of the deep storage slot between a retaining position and a releasing position. The retaining position engages a front storage cartridge to retain the storage cartridge(s) within the deep storage slot based on the bias of the storage cartridge(s) in the direction of the front opening of the deep storage slot, and the releasing position disengages the front storage cartridge to facilitate movement of the one storage cartridge(s) within the deep storage slot based on the bias of the storage cartridge(s) in the direction of the front opening of the deep storage slot.
摘要:
A method, system, and computer program product for sensing the presence and/or misplacement of mechanical sub assemblies (MSAs) within storage slots of automated storage libraries. Each MSA is tracked based on signed empty cell barcode labels. Signed empty cell barcode labels are utilized to uniquely identify the frame, column, and row coordinates of one or more MSAs. The storage library automatically scans all signed empty cell barcode labels utilizing a scanner mounted on a robotic device. The system provides a counter for each MSA, allowing the storage library to track the usage of the MSA. As usage of the MSA reaches a predefined lifecycle, the library automatically generates an alert to replace the MSA. When a MSA is rearranged within the storage library, the library automatically maps the new frame, column, and row coordinates of the MSA. The counter dynamically modifies the usage count of the MSA according to the unique cell barcode label, thereby tracking all current and previous cartridges, and/or other items that may be scanned during MSA activity.

An apparatus for transporting a storage media cartridge in a data storage library is disclosed. The apparatus includes an accessor, a pinion and a rack having a straight section and a curved section. The curved section includes multiple rack teeth that are capable of rotating independently from each other to allow the pinion to travel along the straight section and onto the curved section of the rack, or vice versa, without any interruption.
摘要:
In an automated library, data cartridges, such as magnetic tape cartridges, are stored in storage cells and accessed by data storage drives. An accessor with a gripper transports cartridges between storage cells and storage drives. Cartridges are prioritized according to their relative importance. A processor manages the placement of the cartridges in cells by having higher priority cartridges stored closer to the front of multi-cartridge cells than cartridges with a lower priority. Cartridges with a higher priority may also be stored closer to a storage drive than cartridges with a lower priority. A pusher may be used to push cartridges towards the front of multi-cartridge cells with an empty position to enable the gripper to reach the front cartridge.

An apparatus for transporting a storage media cartridge within a data storage library is disclosed. The apparatus includes a first pair of rack and guide rail, a second pair of rack and guide rail, and an accessor capable of moving on the first pair of rack and guide rail or the second pair of rack and guide rail. The first pair of rack and guide rail is located orthogonally from the second pair of rack and guide rail. Located at an intersection between the first pair of rack and guide rail and the second pair of rack and guide rail, a turn plate may change a moving direction of the accessor. The turn plate includes two racks and four guide rails with a conical shaped rack tooth located at an intersection of the two racks.
摘要:
A method to transfer information between data storage devices. The method provides an information storage assembly comprising a frame, a memory device disposed on that frame, information written to that memory device, a power supply removeably attached to the frame, and a first data storage device comprising a first identity removeably attached the frame. The method writes first configuration information to the memory device. If the method detects an error in the first data storage device, then the method removes the first data storage device from the frame. The method further provides a replacement data storage device, removeably attaches that replacement data storage device to the frame, and determines if the replacement device uses the first configuration information. If the replacement device uses the first configuration information, then the method provides the first configuration information to the replacement data storage device from the memory device.

Data storage libraries as disclosed that provide for accessors that turn upon angled rails. In the library, a first rail and a second rail form an angle. The first and second rail each have a drive surface, but the drive surfaces are on different vertical planes. A switching mechanism of the accessor is then configured to move a drive mechanism between the different vertical planes of the drive surfaces. If the switching mechanism positions the drive mechanism adjacent to the drive surface of the first rail, then the drive mechanism engages the drive surface of the first rail to move the accessor along the first rail. If the switching mechanism switches the position of the drive mechanism adjacent to the drive surface of the second rail, then the drive mechanism engages the drive surface of the second rail to move the accessor along the second rail.
摘要:
A system and method to automatically provide frame count, frame identification and status information to each frame within a modular, multi-frame tape library system. In the exemplary embodiment, signals are generated by each frame that have a delay value specific to each frame, which are accumulated and supplied to each frame to determine the total number of frames within the tape library system. A reference pulse is generated by each frame and compared to the delay signal generated by each frame to determine its own identification among the plurality of individual frames. Similarly, a status signal is generated by each frame and supplied to each frame which is indicative, for example, of a door open or other anomaly that can be monitored by all the frames within the tape library system. In the exemplary embodiment, each frame is adapted with a pulse generator and delay signal generator as well as a status register, and each frame is coupled together along a multi-channel bus for carrying the signals generated by each frame.
