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.

Library apparatus having interconnected cell drum and door locking

A library apparatus for storage media such as optical disks includes a rotatable cell drum having several columns of cells for storing the storage media, a load/unload device for inserting and removing cartridges one at a time, at least one drive for reading from or writing to selected media, and an accessor which moves the storage media between the load/unload device and the cell drum, and between the cell drum and the drive. The load/unload device rotates in a collinear arrangement with the cell drum, and can rotate in unison with the cell drum, or independently of the cell drum. The collinear arrangement of the cell drum and the load/unload device reduces the overall size of the library.
