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： An optical disc has a data management area in a region on a radially inward side. Management information is recorded in the data management area as recording marks and spaces. The optical disc also has a data recording area on the outside of the data management area. Data to be read is recoded in the data recording area as recording marks and spaces. The information readout density of the data recording area is higher than that of the data management area. The read power of a readout laser beam during readout can be set smaller in the data management area than in the data recording area. In this manner, the read stability is significantly increased without reducing the information readout density.

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.

摘要： An optical recording medium including recording and reading layers and a servo layer increases the recording capacity thereof. In the optical recording medium including the plurality of recording and reading layers and the servo layer, the servo layer has a groove and a land that can be used to perform tracking control with a long-wavelength servo beam. Information is recorded on the recording and reading layers with a recording and reading beam having a wavelength shorter than the wavelength of the servo beam. Recording marks are formed on the recording and reading layers while both the groove and land are tracked.
