A data storage system comprises a plurality of cartridge receiving devices provided within the data storage system. A cartridge engaging apparatus having a cartridge access side and a back side is mounted within the data storage system so that the cartridge engaging apparatus moves along a displacement path. The arrangement of the plurality of cartridge receiving devices and the displacement path is such that at least one of the plurality of cartridge receiving devices is located opposite the back side of the cartridge engaging apparatus.
