摘要： PROBLEM TO BE SOLVED: To provide a medium structure for reducing a track for a three dimensional pit selection type disk and an optical disk drive compatible therewith. SOLUTION: A plurality of data pit strings are prepared between track guide grooves, and a disk is configured to form a phase change recording film only in the data pit string. A normal resolution signal cancellation is achieved by setting reflectance and phases of a space section and a mark section properly, and deterioration of data cross talk and a push-pull signal is prevented. An optical disk drive configured to read wobble address information after selecting a signal from a push-pull signal of a main beam and a push-pull signal of a sub-beam is used for the optical disk medium of this invention.

摘要： The optical recording medium includes a first information layer including a first recording film having an extinction coefficient of 0.4 or less at a wavelength of a laser beam used for recording and reproducing, and a second information layer including a second recording film consisting essentially of the same constituent elements as those of the first recording film and having an extinction coefficient of 0.4 or less. Among the first and second information layers, the first information layer is located further away from a laser beam-incident surface than the second information layer located closest to the incident surface. The first information layer further includes a light absorbing film having an extinction coefficient of 1.5 or more at the wavelength of the laser beam, the extinction coefficient of the light absorbing film being greater than that of the first recording film.
