Optical recording medium

Abstract

An optical recording medium including two recording layers, each containing an organic dye includes: a first disk substrate formed by laminating a first recording layer and a translucent intermediate layer sequentially on a first transparent substrate made of polycarbonate or the like; and a second disk substrate formed by laminating a reflective layer, a second recording layer, and an interface layer sequentially on a second substrate. The first and the second disk substrates are laminated with a transparent adhesive layer interposed therebetween in a manner that the translucent intermediate layer faces the interface layer. A reflectivity (R1) at a portion of a recording mark formed on any of the first and the second recording layers becomes higher than a reflectivity (R0) at a portion on the recording layer where the recording mark is not formed (R1>R0).

Dependencies are inferred from the claim text.
