摘要:
An optical recording media has a disc substrate and two or more recording layers arranged apart from each other with a dielectric layer interposed therebetween to cause optical change simultaneously by irradiation with light, in which a first recording layer positioned near the disc substrate has a higher optical change temperature and a higher extinction coefficient compared with those of a second recording layer and a later recording layer.
