Abstract:
An automated library (30) handles a plurality of data storage units (e. g. , data cartridges) stored therein. The library comprises an octagonal drum-like member (34) mounted above a library frame (32). The drum (34) has a plurality of faces on an exterior periphery thereof, each for selectively accommodating a cartridge rack (62). Each face of the drum has a rack mount (110) selectively attachable thereto. The library further comprises a rack (38) for accommodating a plurality of modular I/O drive-containing drawers (64). A picker device (80) engages and transports data cartridges between drives (320), an active rack (60), and an entry/exit port transport (500). The entry/exit transport device (500) transports a selected cartridge between a predetermined position in the cabinet and the entry/exit port (100). The entry/exit transport device (500) is both rotatable and extensible. A picker move method and library inventory method are also provided.
