A cartridge assembly for a data storage disk includes a housing for containing the data storage disk inside the housing. The housing defines a plurality of openings for exposing a portion of the data storage disk. An external shutter is supported by the housing on the outside of the housing. The external shutter is moveable between a closed position and first and second open positions disposed on opposite sides of the closed position. According to another aspect, a cartridge assembly for a data storage disk includes a casing and a moveable member disposed to slide on the casing. At least one of the casing and the moveable member includes protrusions or equivalent structure for holding the moveable member in a closed position and in one or more open positions. A method of making a ready-to-use data storage disk cartridge assembly provides other advantages.
