摘要： An optical disc has a first transparent substrate and a second substrate. The first substrate has a first surface and an opposing second surface. The first surface is a beam incidence surface for a laser beam in recording or reproduction of data. The second surface has first concave sections and first convex sections alternately formed thereon. The first concave sections are closer than the first convex sections to the beam incidence surface. The first convex sections have first top portions and first bottom portions closer than the first top portions to the beam incidence surface. First pre-pits carrying auxiliary information related to the data is formed on the first top portions. Each first top portion has a first width orthogonal to a direction of tracks on the first substrate. A second width orthogonal to the above direction between two first top portions of adjacent first convex sections having a first concave section therebetween is narrower than the first width. The second substrate has second concave sections and second convex sections alternately formed thereon. The second concave sections are closer than the second convex sections to the beam incidence surface. The second convex sections have second top portions and second bottom portions closer than the second top portions to the beam incidence surface. Second pre-pits carrying auxiliary information related to the data is formed on the second top portions. Each second top portion has a third width orthogonal to the above direction on the second transparent substrate. A fourth width orthogonal to the direction of tracks between two second top portions of adjacent second convex sections having a second concave section therebetween is narrower than the third width. Recording layers are formed on the first concave and second concave sections. The recording layers are formed in order between the substrates.

The first substrate has a first surface and a second surface. The first surface is a beam incidence surface for a laser beam in recording or reproduction of data.

The first recording layer and the first reflective layer are stack in order on the second surface via the first concave and convex sections. The second structure includes at least a second substrate, a second reflective layer, and a second recording layer. The second substrate has a second concave section and a second convex section formed thereon. The second reflective layer and the second recording layer are stack in order on the second substrate via the second concave and convex sections. The first and second structures are bonded to each other so that the first reflective layer faces the second recording layer, the first concave section becomes closer to the beam incidence surface than the first convex section does, and the second concave section becomes closer to the beam incidence surface than the second convex section does. The first recording layer has a first data-storage area on the first concave section. The second recording layer has a second data-storage area on the second concave section. Each of the first and second convex sections has at least one pre-pit formed thereon. The pre-pit carries auxiliary information related to the data to be recorded or reproduced.

摘要： An optical disk consists of a first laminated layer structure and a second laminated layer structure. The first structure has a first transparent substrate having a first surface and a second surface on both sides thereof, provided on the first surface being a light-incident plane via which a light beam is to be incident in recording or reproduction, formed alternately on the second surface being a plurality of first lands and first grooves, and a first organic-dye recording layer formed on the second surface to cover the first lands and grooves. The second structure has a second substrate, alternately formed on which are a plurality of second lands and second grooves, a reflective film formed on the second transparent substrate to cover the second lands and grooves, and a second organic-dye recording layer formed on the reflective film to face the second transparent substrate. The first and the second structures are bonded to each other via a bonding layer so that the first and second recording layers are provided between the first and second substrates. A formula α1≧cos−1(20/Tb) is satisfied in which Tb is a thickness of the reflective film formed on a bottom of each second groove and α1 is an angle between a plane passing through an upper surface of each second land and a side wall of each second groove.

摘要： When an LPP (land pre-pit) is formed between shallow grooves or shallow pits, the LPP is formed on a land existing between the shallow grooves or the shallow pits. Further, the LPP is formed in a position displaced from a centerline of the land in the radial direction by a predetermined amount. Furthermore, a laser beam power utilized for forming a shallow groove or a shallow pit adjacent to the LPP is reduced so as to be lower than a regular laser beam power.
