ABSTRACT:
When initializing first and second information layers on a phase-change optical disk of the one-side multilayered configuration, a mistake occurs depending on thin film configuration of first and second information layers. The phase-change optical disk having a plurality of information layers having at least a recording layer of generating optically detectable reversible change between an amorphous phase and a crystalline phase on a transparent substrate by irradiation of an energy beam and having an optical separation layer formed between the information layers, wherein initialization start positions of crystallizing said plurality of information layers vary by irradiating a laser beam thereon.
