Abstract
The present invention provides a disc cartridge for enclosing an optical disc rotatable therein. The disc cartridge includes an upper shell connected to a lower shell. The upper shell includes a center portion, a window portion surrounding the center portion and a frame surrounding the window portion. The upper shell is formed using a two-shot injection molding process in which a window portion is injection molded and a center opening is formed in the window portion. The center portion and the frame are formed substantially simultaneously by injection molding a common material within the center opening and around the perimeter of the window portion.
