Abstract:
An optical recording and reading method capable of enhancing the design flexibility of recording layers of an optical recording medium and performing accurate optical recording and reading operations. A basic recording layer is arranged in a position that is in the range of 90 μm to 110 μm away from a light incident surface of an optical recording medium, and recording layers are arranged in parallel with the basic recording layer. At least the position information of the recording layers is recorded in one of the basic recording layer and the recording layers.
