Abstract
A library apparatus having a rotatable cell drum adapted to store a plurality of recording media cartridges, the cell drum having a plurality of columns and each column having plural cells configured to receive the recording media cartridges. The library apparatus further includes a door configured to selectively provide direct operator access to all of the cells of a selected column without the assistance of a media transport device. The library apparatus is provided with a cell drum locking mechanism configured to selectively lock the cell drum and prevent rotational movement of the cell drum, and a door locking mechanism configured to selectively lock the door and prevent opening of the door. A link operably interconnects the drum locking mechanism and the door locking mechanism such that the cell drum locking mechanism must assume a locked state before the door locking mechanism may assume an unlocked state.
