A manufacturing method and an optical information recording medium

The optical information recording medium of the present invention, (a m, 2 or more integers.) Of at least m layer comprises an information layer of the information layer, non between the optically different states A and B including a recording layer that changes reversibly. If an information layer of the first to m-th information layer of m layers from a laser beam incidence side, the information layer of the j (j is an integer satisfying 1 ≦ j ≦ m-1.) Included in the recording recording layer of the j layer, the transmittance of the j information layer when the recording layer of the j is the state a TAj (%), the information of the j when the recording layer of the j is the state B When the transmittance of the layers and TBj (%), information layer of the j is 0 ≦ | TAj-TBj | / (TAj, TBj) max ≦ 0.10 (however, (TAj, the TBj) max, and TAj it is that the value of the larger of the TBj.) satisfy the relationship. Furthermore, at least one recording layer among the first to m-1 of the recording layer, the recording layer and the complex refractive index of the m (refractive index n, n-ik when the extinction coefficient was k) of It is formed by different materials.
