Abstract: A method is disclosed 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. 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.

Abstract: 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.

Abstract: 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.

Abstract: An apparatus to generate a spring force increasing in accordance with a quantity of tape media cartridges stored in a deep slot cell. The apparatus may include a deep slot cell, a biasing element including a torsion spring, and an advancement element. The deep slot cell may store one or more cartridges. The biasing element may generate a spring force toward the front of the deep slot cell such that the spring force generated increases in accordance with a number of cartridges stored in the cell. The advancement element may be positioned to apply the spring force to the cartridges, thereby advancing the cartridges toward the front of the deep slot cell.

Abstract: Disclosed is a deep storage slot with a constant spring force comprising a storage slot housing defining a cartridge cavity and a cartridge opening, wherein the cartridge cavity is configured to store a plurality of cartridges in depth. Also disclosed is a constant force spring comprising a rolled, pre-stressed strip that exerts a constant force to resist uncoiling, the constant force spring having a first end affixed to the storage slot housing within the cartridge cavity to direct the constant force towards the cartridge opening, and at least one retention feature configured with the storage slot housing to hold at least one of the plurality of cartridges within the cartridge cavity against the constant force.

Abstract: 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.

Abstract: 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.

Abstract: A system of shipping tape drives while they are mounted to a frame uses shipment brackets to retain the drives within the frame in retracted positions during shipment. The brackets allow the drives to be shipped inside the frame. The brackets hold the drives in the retracted position within the frame by clipping into the drives and the shelves above the drives. Tabs on each bracket snap into a drive such that the drive cannot move with respect to the bracket or the shelf. The drive is pushed into position until the bracket is fully engaged with the shelf above the drive and the tabs have prevented the drive from further insertion. Because the bracket is engaged, the drive no longer can move in or out of the shelf.

Abstract: A deep slot tape cartridge library module including a main wall having two major surfaces; a pair of side walls in spaced relation to each other and each extending orthogonally to both major surfaces whereby the main wall and side walls form a substantially “H” shaped structure; an opening in the main wall, the opening extending longitudinally along the main wall a relatively short distance; a spring clip configured complimentarily to the opening and removably retainable therein; and a spring fixedly connected to the spring clip. A method for replacing a spring of a high density tape library where a spring assembly and main wall are utilized, the method including identifying a slot having a failed spring; emptying the identified slot of tape cartridges; extracting the spring assembly from the main wall; and replacing the spring assembly with a non-failed spring assembly.

Abstract: 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 vertical mast is pivotally coupled to the accessor base and the a gripper mechanism is translationally coupled to the vertical mast. The gripper mechanism is operable to translate relative to the vertical mast in a vertical direction within the automated data storage library, and the vertical mast is operable to pivot the vertical mast and the gripper mechanism relative to the accessor base.

Abstract: A hinged flap including an angled surface and a flat surface prevent the incorrect loading of a 3592 data cartridge into a dedicated pass-through slot. The angled surface of the hinged flap is pushed by a recessed angled surface in the front face of the 3592 data cartridge to force the hinged flap out of the slot, allowing the cartridge to be inserted. In the absence of the recessed angled surface in the front face of the data cartridge, the flat surface of the flap blocks insertion of the data cartridge.

Abstract: An automated data storage library provides for reducing inventory after media access. Media is moved, inserted, or removed without opening the access door normally associated with accessed media. A media status of a data storage drive within the automated data storage library is checked. An unexpected condition is detected at the data storage drive. An inventory of at least part of the library is performed for the unexpected condition. Alternately, a move operation is initiated for a data storage media wherein an unexpected condition is detected at the source and/or target location of the move operation. An inventory of at least part of the library is performed for the unexpected condition.
