FORMING METHOD OF INFORMATION RECORDING LAYER ON OPTICAL RECORDING MEDIUM, AND MANUFACTURING METHOD OF OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a multilayer optical disk that can suppress cost increase to the minimum and realize a large capacity. SOLUTION: First, a first information recording layer 108 is formed on a base plate 104. On the other hand, a light transmissive resin stamper 140 having fine asperities (the second recording layer for transfer) 142 to transfer the second information recording layer 114 is formed separately. Both 104 and 140 are adhered together through the first ultraviolet-rays curable light transmissive layer 110. Then, removing the stamper, the second light transmissive layer 116 is formed on the supper surface of the second information recording layer transferred and formed on the first light transmissive layer 110. The laser beam La is radiated from the second light transmissive layer 116 to record and/or reproduce information signals on the first and the second information recording layers 108 and 114.
