发明名称 STAMPER AND METHOD FOR INJECTION MOLDING INFORMATION BEARING MEMBER
摘要 An improved stamper and method involved in the replication of optically-readable information bearing members by means of an injection molding process utilizing a stamper having a conformal layer of chromium electrolytically deposited over the encoded surface of an existing optically-readable information bearing nickel stamper. Nickel stampers produce replicas having structural and optical defects affecting playability of the replica. The present invention provides improvement in the reduction or eliminating of "plowing" and "orange peel" defects through cleaner release at the interface of the master stamper and the stamped article. The invention involves an improved stamper surface comprised of a thin layer of chromium metal oeposited over an existing nickel stamper. Such a surface insures a cleaner release at the interface of the master stamper and stamped article.
