ABSTRACT:
A process for producing an information carrier containing recorded audio and/or video information wherein a web of a thermoplastic material is extruded onto the patterned surface of a metal master and pressure is applied to force said thermoplastic material into contact with the metal master. The thermoplastic material is cooled to a temperature below its softening point to form an imaged thermoplastic web which is separated from the metal master. Then a thin film of metal particles is deposited on the imaged surface of the thermoplastic web and said metallized thermoplastic web is laminated with a substrate carrying an uncured coating of a radiation curable resin. The resin is cured and individual information carriers are separated from the web of information carrying laminate. A center hole is placed in the separated individual information carriers, when appropriate.
