Document Type and Number:
Japanese Patent JP4276116
Kind Code:
B2
Abstract:
The invention relates to a method of manufacturing a multilayer optical disc which is not formed with voids in an optically transparent zone, and a multilayer optical disc. The method of manufacturing a multilayer optical information recording medium having at least a first and a second information recording layer includes the steps of forming the first information recording layer, applying a porous resin film on the first information recording layer, impregnating the porous resin film with a liquid functional resin, bringing a stamper into pressure contact with the porous resin film and curing the functional resin, and removing the stamper so that the second information recording layer is formed on the substrate.
