ABSTRACT:
An apparatus and process for attaching a protective thin film layer to a surface of a compact disc stamper are disclosed. An apparatus for carrying out the process comprises a base for supporting the compact disc stamper, a supply roll for providing the thin film protective layer to the compact disc stamper, and at least one bladder for inflating. The bladder is operative to be inflated against the protective layer for pressing the protective layer against the compact disc stamper. The apparatus may also include a mechanism for directing a vacuum induced suction force against the underside of the compact disc stamper for securing the same to the base while attaching the thin film protective layer to the compact disc stamper.
