The cartridge magazine comprises at least one cell configured to accommodate a cartridge of information storage media. The entry/exit port (200) is configured to permit selective passage of the cartridge between an exterior of the frame and the at least one cell, the passage being through an aperture provided in the frame. The entry exit port (200) comprises an entry/exit port handle (210) and a cartridge caddy (220). The entry/exit port handle (210) is configured both for selective closure of the aperture and selective translation with respect to the frame for opening the aperture. The cartridge caddy (220), to which the handle (210) is attached, is configured to carry the cartridge out of the at least one cell and through the aperture upon translation of the handle (210).
