Patent ID: 6982944

Claim:
An optical information-recording medium comprising: a substrate which includes a land, a groove having a flat bottom surface, and in-groove pits having flat bottom surfaces, respectively, formed on one surface of the substrate; a recording layer which contains an organic dye and is formed on the one surface; and a reflective layer which is formed on the recording layer, wherein: dp/dg<Tp/Tg is satisfied provided that dg represents a depth from a land surface of the substrate to the bottom surface of the groove, dp represents a depth from the land surface of the substrate to the bottom surface of the in-groove pit, Tg represents a recess depth of the recording layer from an interface between the recording layer and the reflective layer on the land surface to the interface between the recording layer and the reflective layer at the groove, and Tp represents a recess depth of the recording layer from the interface between the recording layer and the reflective layer on the land surface to the interface between the recording layer and the reflective layer at the in-groove pit.
