OPTICAL INFORMATION RECORDING METHOD AND MEDIUM |
摘要 |
<p>A method for optically recording information on an optical information recording medium comprising a light transmitting substrate (1), a light absorptive layer (2) overlaying the substrate to absorb a laser beam and a light reflective layer (3) overlaying the light absorptive layer, which comprises energizing the light absorptive layer by a laser beam entered through the light transmitting substrate, and locally deforming, by the energy thereby generated by the light absorptive layer, a surface layer of the substrate adjacent to the light absorptive layer, to form optically readable pits in the surface layer of the substrate.</p> |
