<P>PROBLEM TO BE SOLVED: To provide a write-once optical recording medium capable of responding to a blue laser wavelength region, utilizing a shallow channel base with good transfer property, and using an organic material with little changes in recording characteristics, a reflective index and the like against changes in recording and regeneration wavelengths, and a method for recording it. <P>SOLUTION: The write once optical recording medium (1) has a laminar structure in which at least an organic material layer having a main absorption band at a non- recording time existing at a longer wavelength side to a recording and regeneration wavelength, and no absorption function to a light of the recording and regeneration wavelength, an optical absorption layer and an optical interference layer are successively laminated on a base. The write once optical recording medium (2) has the laminar structure in which at least the optical interference layer, the optical absorption layer, the organic material layer having the main absorption band at the non-recording time existing at the longer wavelength side to the recording and regeneration wavelength, and no absorption function to the light of the recording and the regeneration wavelength, and a cover layer are successively laminated, and recording and regeneration are performed from the cover layer side. <P>COPYRIGHT: (C)2004,JPO |
