Abstract:
The optical information recording medium comprises a recording layer on a surface of a support. The surface of the support has pregrooves with a track pitch ranging from 50 to 500 nm, the recording layer comprises an azo metal complex dye, the azo metal complex dye is a complex of one or more azo dye and transition metal ions of which number is equal to or greater than the number of the azo dye. The azo metal complex dye comprises two or more transition metal ions per molecule, and in a molecule of the azo metal complex dye.
