A cartridge library (30) comprises at least one drive (60); a cartridge magazine (52) comprising at least one cell configured to accommodate a cartridge of information storage media; and a transport mechanism (54) configured to transport the cartridge between the magazine (52) and the drive (60). The transport mechanism (60) is configured to transport the cartridge in a first linear direction toward and away from the cell and in a second direction orthogonal to the first direction. The transport mechanism comprises two cartridge engagement hooks (310) carried by the transport mechanism. Each hook (310) engages a recessed feature (500) of the cartridge when the cartridge is between the two hooks (310). A distal end of each hook is also configured so that the hook withdraws from the recessed feature of the cartridge when the transport mechanism travels in the second direction and the cartridge is in the at least one cell.
