A storage library which enables capacity expansion without additional robotics hardware includes a frame, first and second modules having respective cells, and a robot. The frame supports the first module at a first frame length position such that the first cells are positioned at the first frame length position and along the periphery of a channel extending within the frame interior through the frame length. The frame supports the second module when the second module is mounted to the frame such that the second cells are positioned at the second frame length position and along the channel periphery. The robot has a support connected to the frame and a picker movably connected to the support. The picker moves through the channel to manipulate media elements held by the first cells, and to manipulate media elements held by the second cells when the second module is mounted to the frame.
