Method and system for sharing robotic mechanisms between automated storage libraries

A storage library system comprising:

• a first storage library having an interior and an exterior, the first storage library having a robotic mechanism transfer port extending between the interior and the exterior of the first storage library, the interior of the first storage library housing a plurality of media object cells each housing a media object, the first storage library having a plurality of interconnected guide tracks which bound the media object cells of the first storage library with one of the guide tracks of the first storage library being connected to the robotic mechanism transfer port of the first storage library, the first storage library further having a first robotic mechanism movable along the guide tracks of the first storage library for accessing the media objects of the first storage library;
• a second storage library having an interior and an exterior, the second storage library having a robotic mechanism transfer port extending between the interior and the exterior of the second storage library, the interior of the second storage library housing a plurality of media object cells each housing a media object, the second storage library having a plurality of interconnected guide tracks which bound the media object cells of the second storage library with one of the guide tracks of the second storage library being connected to the robotic mechanism transfer port of the second storage library;
• and
• a guide structure routed between the exteriors of the first and second storage libraries from the robotic mechanism transfer port of the first storage library to the robotic mechanism transfer port of the second storage library, wherein the first robotic mechanism is movable from the guide track of the first storage library connected to the robotic mechanism transfer port of the first storage library along the guide structure to the guide track of the second storage library connected to the robotic mechanism transfer port of the second storage library in order to move along the guide tracks of the second storage library for accessing the media objects or the second storage library.
