Production method of multi-layer information record carriers










Image Number 2 for United States Patent #6797090.

A production method of multi-layer information record carriers that involves forming a signal duplication layer on a substrate that contains signals, then replacing a metallic stamping plate with the substrate that comprises the signal duplication layer for manufacturing a signal layer of high molecular materials. After the signal layer has been subjected to curing by exposure to ultra violet light, the signal layer is separated from the signal duplication layer because of the difference between the adhesive forces of the different materials. Multi-layer information record carriers can be manufactured by repeating the manufacturing process. Since the manufacturing process of the invention is simple and speedy, it facilitates the creation of automated facilities for mass production.
