ABSTRACT:
A molded center core for a flexible recording disc and a related method of manufacture are provided. The disc includes a recording media sandwiched between an injection molded center core having a metal insert, and an injection molded ring. The core and ring are ultrasonically welded to hold the media in place. The method includes the steps of: injection molding a separate plastic center core with a metal insert therein; injection molding a separate plastic ring; locating the center core/insert combination in the central opening of the recording media to abut a first surface of the media; locating the molded ring on the center core to abut a second, opposite surface of the media; and permanently connecting the core and ring.
