OPTICAL RECORDING MEDIUM, OPTICAL RECORDING METHOD AND OPTICAL REPRODUCING METHOD

摘要

The optical recording medium comprises a substrate, an in-groove and an on-groove, and further, a recording layer and a cover layer formed in this order on at least one surface of the substrate, wherein the recording layer is formed plane-wise and has an almost uniform thickness and the in-groove is an optical recording section. The optical recording method comprises applying the converged light to record information in an optical recording section. The optical reproducing method comprises applying the converged light and detecting the reflected light to reproduce the information stored in the optical recording section.
