    摘要: An original optical disk which is suitable for mass production and facilitates the densification of the optical disks by improving the transferability and the releaseability of an optical disk substrate with respect to a stamper, comprises concavities which constitute pits or grooves along tracks and which include side walls, along the track direction of the concavity, having inclinations such that a width of an opening between sidewalls decrease closer to the base of the concavity in the track width direction of the concavity becomes and such that the inclination has at least one inflection point so that the closer to the bottom side, the sharper the inclination becomes and the closer the opening edge side, the milder it becomes.

    摘要: An optical disk has first and second substrates, at least one of which is provided with optically readable pits corresponding to record data, and a reflection film coated on the pits. In the optical disk, the first and second substrates are laminated on each other such that the surface on which the pits are formed, is located inside. Label information, indicative of the record data, is formed on at least one of the surfaces of the first and second substrates, which contact each other.
