Abstract

An optical recording medium having a plural number of recording layers includes a n-th recording layer () (n≧1), made up by a substrate () and a semi-reflective layer () carried by the substrate () and adapted for partially reflecting and partially transmitting the incident light, a (n+1)th recording layer (), made up by another substrate () and a reflecting layer () carried by the substrate () and adapted for reflecting the incident light, and a light condensing layer () for condensing the light incident via the n-th recording layer () on the (n+1)th recording layer ().
