摘要： An optical information-recording medium, which is provided with a substrate and a light-absorbing layer formed of a dye material on the substrate, includes a user information area in which a concave/convex pattern including spiral-shaped or concentric grooves are formed, and BCA which is provided on an inner circumferential side of the user information area and in which information is recorded with a bar code, wherein a concave/convex pattern, which is different from the concave/convex pattern in the user information area, is formed in BCA. With this construction, an optical information-recording medium, on which BCA information is reproduced without performing any tracking, is provided, wherein a BCA reproduced signal having a satisfactory signal quality is obtained from BCA.

摘要： 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).
