Abstract
Abstract An insertable drawer member configured and dimensioned for receiving and storing digitally coded discs within an outer housing in a manner which ensures that information bearing areas of said discs are not damaged during insertion or removal therefrom, the insertable drawer member comprising: a base at least partially defined by a pair of opposed side walls, having upon its surface a semicircular groove configured for the insertion of a portion of the digitally coded disc by pressure contact, wherein only a non-information-bearing surface portion of the disc is ever contacted by the drawer member. The drawer member further comprises a lid integrally formed with the base and provided upon at least a portion of a front face thereof with a serrated gripping area to facilitate grasping and moving the drawer member to access the disc. A lower edge of the lid is configured for contact relation with an abutting V-shaped upper edge portion of the outer housing. The drawer member is additionally provided with means for retaining at least a portion thereof within the housing, which are operatively associated with corresponding means located upon an inner surface of the housing.
