Abstract: In an automated data storage library having a plurality of multi-cartridge deep slot cells, each configured to store a plurality of data storage cartridges arranged in sequential order of tiers from front to rear, and having accessor(s) configured to selectively extract, place and transport cartridges with respect to the cells; operating the accessor(s) to selectively extract, place and transport cartridges with respect to the cells and with respect to other elements of the library. If all tiers of the selected cells except the rearmost tier are full, added cartridges are placed to fill the rearmost tier of an evenly spread selection of the cells.

Abstract: In an automated library, data cartridges, such as magnetic tape cartridges, are stored in storage cells and accessed by data storage drives. An accessor with a gripper transports cartridges between storage cells and storage drives. Cartridges are prioritized according to their relative importance. A processor manages the placement of the cartridges in cells by having higher priority cartridges stored closer to the front of multi-cartridge cells than cartridges with a lower priority. Cartridges with a higher priority may also be stored closer to a storage drive than cartridges with a lower priority. A pusher may be used to push cartridges towards the front of multi-cartridge cells with an empty position to enable the gripper to reach the front cartridge.
