INITIALIZATION METHOD FOR INFORMATION RECORDING MEDIUM, INITIALIZATION APPARATUS FOR INFORMATION RECORDING MEDIUM, AND INFORMATION RECORDING MEDIUM |
摘要 |
According to the present invention, a recording film is partially initialized using a first light beam (A) having a wavelength for initialization, focus adjustment is performed using a second light beam (B) having a wavelength corresponding to a wavelength for recording and reproducing information on and from an information recording medium, and then the recording film is initialized using the first light beam (A), thereby it is possible to securely initialize recording films of all information layers of a multilayer information recording medium.
