ABSTRACT:
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.
