PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical recording medium capable of uniformizing hardening of an adhesive. SOLUTION: In this manufacturing method, first a substrate 8 is formed. A signal pit and a dummy pit are formed respectively in regions corresponding to a signal area 2 and a blank area 3 respectively of a surface as a signal surface 8b of the substrate 8. Then a substrate 12 is molded by an injection molding method and the like. At this time, a dummy signal pit and a dummy pit are formed respectively in regions corresponding to a dummy signal area 6 and a blank area 7 respectively of a surface as a dummy signal surface 12b of the substrate 12. Then, a reflecting film 9 and 10 are formed respectively on the signal surface 8b of the substrate 8 and the dummy surface 12b of the substrate 12 respectively. Then the reflecting film 9 of the substrate 8 and the reflecting film 10 of the substrate 12 are made to face each other and an adhesive is held therebetween. Then a side of a reading surface 8a of the substrate 8 and a side of a label printing surface 12a are irradiated with an ultraviolet ray to harden the adhesive. |
