Apparatus and method for producing optical recording medium, optical recording medium, apparatus and method for reproduction and apparatus and method for recording
Abstract:
An optical recording medium having a plural number of recording layers includes a n-th recording layer (23) (n≧1), made up by a substrate (20) and a semi-reflective layer (21) carried by the substrate (20) and adapted for partially reflecting and partially transmitting the incident light, a (n+1)th recording layer (28), made up by another substrate (25) and a reflecting layer (26) carried by the substrate (25) and adapted for reflecting the incident light, and a light condensing layer (24) for condensing the light incident via the n-th recording layer (23) on the (n+1)th recording layer (28).
