性が高く、低コスト化が期待できるなどの利点がある。[Prior art and problems to be solved by the invention] Until now, optical information recording media have been proposed in which a recording layer made of a low melting point metal or a low melting point metal and a dielectric is provided on a substrate. , these have disadvantages such as poor storage stability, low resolution, low recording density, difficult manufacturing conditions and high cost. Therefore, it has recently been proposed to use an organic dye thin film as the recording layer in place of the metal thin film. This organic dye thin film has a low melting point, low decomposition temperature, and low thermal conductivity, so it has the potential for high sensitivity and high density, and because film formation can be done by coating, it is highly mass-producible and expected to be low cost. There are advantages such as being able to

However, if necessary, an undercoat layer may be provided between the substrate and the recording layer, or a protective layer may be provided on the recording layer. Alternatively, the pair of recording media configured in this manner may be formed into an air sandwich structure in which the recording layer is placed inside and sealed with another substrate through a space, or a tight sandwich structure in which the pair of recording media is bonded through a protective layer. It may also be a laminated structure.
