In the present invention, in the optical recording medium having a recording layer composed mainly of organic dyes on a substrate, the organic dyes have a first maximum of absorption at a wavelength? 1 of 400 nm or less in the absorption spectrum, and Characterized by having a second maximum value of absorption on the longer wavelength side than [lambda] l, and having a refractive index n and an absorption coefficient k of the organic dye satisfying n≥1.90 and 0.03≤k≤0.30. An optical recording medium is disclosed. |
