Abstract:
An optical recording medium includes: N recording layers (where N≧4); a number of kinds of layer intervals between the recording layers adjacent to each other being an integer M equal to or less than a minimum integer equal to or more than log2(N); and one or more AB blocks including four recording layers with a first layer interval A, a second layer interval B, and the first layer interval A formed in order in the one or more AB blocks. When the M as the number of kinds of layer intervals is M≧3, the optical recording medium has a part of a third layer interval C as a layer interval between a recording layer forming an AB block and a recording layer adjacent to the recording layer, the adjacent recording layer being included in other than the AB block including the recording layer.
