Briefly, one such method comprises the steps of: receiving information associated with one of the plurality of data media located in the drawer; based on the information associated with one of the plurality of data media, determining the corresponding predefined position relative to the opening in the data storage system; and positioning the drawer in the predefined position relative to the opening in the data storage system.

Abstract: A cartridge access device in a cartridge storage system is designed to retrieve a cartridge from a storage device and to transfer the cartridge to a particular location within the system. Once the cartridge is no longer needed at the particular location, the cartridge access device retrieves the cartridge from the particular location and returns the data cartridge to the storage device. The data cartridge device preferably includes at least two engaging members that engage a respective surface of a frame assembly. Channels in the surfaces of the frame assembly guide the engaging members and, therefore, the cartridge access device as the cartridge access device moves. The engaging members are engaged with a respective conductive track member that extends through the channels in the frame assembly.

Abstract: In general, the present invention provides an autochanger device having a cavity for receiving a magazine containing a media cartridge, wherein a retention arm of the cavity retrains the media pieces within the magazine while the magazine fills the cavity. In particular, a detent mechanism attached to the magazine interacts with the retention arm of the library, via a magazine transport handle, to secure media cartridges contained within the magazine as the magazine is received by a cavity of the autochanger.

Abstract: A cartridge handling system for storing and accessing at least one data cartridge according to the present invention may comprise a frame that defines at least one curvilinear cartridge access side. A curvilinear guide member is mounted to the frame so that substantially all points along the curvilinear guide member are positioned an equal spaced distance from the curvilinear cartridge access side defined by the frame. A cartridge access device is mounted to the curvilinear guide member so that a cartridge access end of the cartridge access device is positioned adjacent the curvilinear cartridge access side defined by the frame at substantially all positions along the curvilinear guide member. An actuator system operatively associated with the cartridge access device moves the cartridge access device along the curvilinear guide member.

Abstract: A cartridge engaging assembly for translating a cartridge is disclosed. The cartridge engaging assembly may include a linearly translatable cartridge engaging device adapted to engage a cartridge, and a first drive assembly operably connected to the cartridge engaging device which is adapted to linearly translate the cartridge engaging device in a lateral direction. A second drive assembly is operably connected to the cartridge engaging device and is adapted to linearly translate the cartridge engaging device in a longitudinal direction. A third drive assembly is operably connected to the cartridge engaging device and is adapted to rotate the cartridge engaging device around an axis. In one embodiment, the cartridge engaging assembly also includes a flip latch assembly, and the second drive assembly and the third drive assembly use the same motor. One or two tracking devices such as a bar code reader may also be included.

Abstract: A cartridge picker assembly may include a frame having a first side wall and a second side wall positioned in spaced-apart relation and a cartridge access end. A lateral guide surface being substantially parallel to a lateral plane is associated with the first side wall of the frame. A thumb assembly is slidably mounted to the first and second side walls of the frame so that the thumb assembly is capable of moving toward and away from the cartridge access end of the frame. A guide member is mounted to the thumb assembly, engaging the lateral guide surface on the first side wall of the frame so that lateral motion of the thumb assembly is controlled as the thumb assembly moves toward and away from the cartridge access end of the frame.
