PROBLEM TO BE SOLVED: To easily produce an information recording carrier for an ultrahigh density memory using the conventional facilities and infrastructure for producing an optical disk. SOLUTION: An information layer 103 is formed on the irregular pattern side of each of irregular patterned substrates 101 with guide grooves, prepits or the like. A protective layer 105 having protecting and lubricating functions is formed on the information layer 103 by coating, sputtering or other method. A hard coat layer 109 of a UV-curing resin or the like is applied on the substrate side and cured by exposure. The resultant two information substrates physically similar to each other are arranged with the information layers 103 outward and stuck to each other with an adhesive layer 107 of a hot melt resin, a thermosetting epoxy resin or the like to obtain the objective information recording carrier for an ultrahigh density memory. |
