ABSTRACT:
A direct entry/exit (DEE) door exposes several cells in the cell drum when the door is open. The DEE door is provided so that several storage media can be placed in or removed from the cell drum at once, either manually or automatically. The library apparatus automatically rearranges the storage media to fill the cells nearest the drive, which reduces the time required to locate storage media in the cell drum and place them in the drive. A locking mechanism locks the DEE door when the cell drum rotates, and locks the cell drum when the DEE door is open. Each cell in the cell drum has a skew mounting preventing mechanism and inverse mounting preventing mechanism which prevent incorrect mounting of a cartridge in the cell drum.
