摘要： A recording method for irradiating a multi-layered optical recording medium with a laser beam to record information thereon. The optical recording medium can form a first information recording layer that is the farthest from a light incident surface, a second information recording layer that is the second farthest from the light incident surface, and at least one third information recording layer that is located closer to the light incident surface than the second information recording layer is. The method is to record information on the second information recording layer when all the information recording layers other than the second information recording layer are either blank or have been completely recorded. This allows for realizing high-quality information recording in consideration of adherence of foreign matters or occurrence of scratches.

摘要： Information is recorded on a multi-layered optical recording medium by irradiating it with a laser beam. The recording medium can form a first information recording layer that is the farthest from a light incident surface, a second information recording layer that is the second farthest from the light incident surface, and at least one third information recording layer that is located closer to the light incident surface than the second information recording layer is. At this time, if all the information recording layers other than the first information recording layer are either blank or have been completely recorded, then information is recorded on the first information recording layer. This allows for stabilizing the energy of a recording laser beam during recording and thereby providing improved recording quality.

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： An information recording method for a multi-layered optical recording medium that can form information recording layers in 3 layers or more. When all the information recording layers are blank, the information recording layer that is the closest to the light incident surface is irradiated with a laser beam to start recording. High quality information recording is thus implemented in consideration of adherence of foreign matters and occurrence of scratches.
