Abstract
A method of fabricating a cartridge for an optical data storage disc includes attaching a plastic shell and a sheet metal cover plate. The shell includes lateral walls and a floor that together define a disc cavity and a plurality of assembly posts. The sheet metal cover plate includes a plurality of holes. To attach the cover plate to the shell, the assembly posts are inserted into the holes, and the ends of the assembly posts are heated to form mushroom caps which hold the cover plate against the shell. The optical disc is housed in the disc cavity, with the data side of the disc facing the cover plate. A sheet metal shutter is wrapped around an edge of the cartridge and over the shell and cover plate.
