Abstract: A data storage library and method of operation are disclosed wherein access at least to part of at least one robotic mechanism from the data storage library's exterior is permitted. Access is accomplished through a service port in the library's housing. Access to the storage cells, and thus the data cartridges sitting therein, from the library's exterior is blocked.

For robotic mechanisms operating on a track, part of the track may be routed through the service port to bring the robotic mechanisms to the exterior of the library for maintenance purposes.

Abstract: A method and system for sharing robotic mechanisms between physically remote storage libraries in an automated storage library system includes routing robotic mechanism guide structures between the storage libraries. The guide structures run through robotic mechanism transfer ports located on the sides of the housing enclosures of the storage libraries. A robotic mechanism within an first storage library moves through the transfer port of the enclosure of the first storage library onto the guide structure. The robotic mechanism then moves out of the enclosure of the first storage library along the guide structure towards a second storage library. The robotic mechanism then moves along the guide structure through the transfer port of the enclosure of the second storage library and into the second storage library for performing operations such as accessing media objects within the second storage library.

Abstract: The present invention is an automated storage library suitable for rack-mount and desktop installations. Storage media cartridges and a robotic mechanism that transport the storage media cartridges internal to the library are mounted on a moveable drawer. With the drawer at an internal position, the robotic mechanism transports the storage media cartridges between cartridge slots mounted on the drawer and read-write media drives and other cartridge handling devices not mounted on the drawer. The drawer is capable of moving through an opening in the storage library housing to an external position where the storage media cartridges and the robotic mechanism are readily accessible. At the external position, the storage media cartridges can be inserted and removed from the cartridge slots. The drawer may be detachable from the housing to allow unobstructed access to the components housed in the interior of the storage library.
