<P>PROBLEM TO BE SOLVED: To provide a multilayer optical recording medium where information can be recorded and reproduced by recording and reproducing light of a short wavelength. <P>SOLUTION: The optical recording medium 100 having two recording layers containing organic dye has a first disk substrate obtained by laminating a first recording layer 102 and a semi-transparent intermediate layer 103 one by one on a first transparent substrate 101 composed of polycarbonate etc., and a second disk substrate obtained by laminating a reflection layer 107, a second recording layer 106 and an interface layer 105 on a second substrate 108. The first disk substrate and the second disk substrate are laminated through a transparent adhesive layer 104 so that the semi-transparent intermediate layer 103 and the interface layer 105 may face each other. Reflectivity (R<SB>1</SB>) at a section of a recording mark formed on the first recording layer 102 or the second recording layer 106 is higher than reflectivity (R<SB>0</SB>) at a section where the recording mark is not formed (R<SB>1</SB>>R<SB>0</SB>). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
