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.

Production method of multi-layer information record carriers

A manufacturing method of a multi-layer optical information record carrier, which has a plurality of layers of reflecting surfaces with pits for recording information. According to the method, a reflective layer is first coated on a stamper with a pit pattern. A radiation-setting adhesive polymer resin is then applied on a substrate with another pit pattern and coated with a partial reflective layer. The substrate and the stamper are combined together and the resin is cured by ultraviolet light. After peeling off the stamper, two reflective layers are formed on the substrate. Finally, two of the substrates are adhered together using polymer resin and one obtains a multi-layer optical information record carrier with dual information layers on both sides.
