Abstract: In a mass storage library, an input/output station for inserting cartridges into and out of the library includes a door pivotally mounted to the station through cams that pivotally rotate a toggle bracket having fingers, one for each cartridge cell in the input/output station. Each cartridge used at least in the input/output station includes a cartridge orientation indicator in the form of a recess at one top edge of each cartridge. After inserting the cartridges into the cells of the input/output station, the door is closed rotating the toggle bracket and its fingers into the recess of each cartridge. The door will close if all of the cartridges have the recess correctly oriented to permit the fingers to clear the cartridges.
