Abstract
An apparatus and method of manufacturing a low cost disc drive base plate that incorporates a platform portion and one or more over-molded disc drive structural components. The platform portion of the base plate is stamped or fine blanked from sheet metal and defines a centrally located depression for receiving over-molded structural components of the disc drive. The structural components of the disc drive are over-molded using a polymer or plastic insert molding process to the platform portion of the base plate. The use of a stamped platform portion having over-molded structural components significantly reduces conventional manufacturing costs and allows for the design of a disc drive having greater positional accuracy then that obtained with current disc drive technology.
