<P>PROBLEM TO BE SOLVED: To provide a method for initializing an optical recording medium, cable of reducing the unevenness in the initialization due to optical interference generated in the initialization, without deteriorating the information recording/ reproducing signal characteristic of a recording layer, in the recording medium having a plurality of optical recording layers. <P>SOLUTION: In initializing the optical recording medium in which at least a first optical recording layer 16 and a second of optical recording layer 12 are stacked on a substrate 11 from the irradiation side with light through an intermediate layer 17, the material constituting the intermediate layer 17 has sufficient transmittance for the wavelength of recording/reproducing light LTR for the optical recording medium, and includes absorbance for the wavelength of initialization light LTI. In the process in which the initialization is performed by irradiating the first optical recording layer 16 with the initialization light LTI, the initialization is performed using a laser beam, as the initialization light, having a wavelength in the range of from 200 nm to 400 nm. <P>COPYRIGHT: (C)2003,JPO |
