Abstract
Abstract A rewritable optical disk is protectively enclosed in a cartridge formed in part by two plastic shells disposed in face-to-face relation and defining a compartment for the disk. A door with shutters is slidable on the shells between open and closed positions relative to access apertures formed in the shells. The shutters are molded integrally with a connecting web to enable the door to be manufactured as a single-piece unit. A tongue molded integrally with the web enables the door to be assembled to the shells with a slip-in fit and coacts with the shells to mount the door for sliding between its open and closed positions.
