摘要： When there is a defect area in a specific recording layer, recording of information is continued and reduction in a recording rate is restrained. In an optical recording method for recording information on a multilayer optical recording medium having a plurality of recording layers by irradiating the recording layer with a beam spot, any recording layer is set as an escape recording layer. When a defect area is detected while information is recorded on another recording layer except for the escape recording layer, the beam spot moves to the escape recording layer to continue recording the information.

摘要： In a multilayer optical recording medium having three or more recording layers, when data is recorded on a recording layer far away from an incident surface of laser light, and especially on a recording layer farthest away from the incident surface of the laser light, by applying the laser light, the recording power margin of the farthest recording layer allows for a variation in the optimal recording sensitivity even if the transmittance of the recording layers located between the laser light incident surface side and the target recording layer is varied due to existing recordings and the amount of the laser light passing therethrough is also varied. In this case, the recording layer which is the farthest from an incident surface of laser light has a phase change recording film, and the recording layer which is the nearest from the incident surface of the laser light has a write-once read-multiple recording film.

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.
