Optical information recording medium, method of recording information and azo metal complex dye

摘要

An aspect of the present invention relates to an optical information recording medium comprising a recording layer on a surface of a support, wherein 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 being a complex of six azo dyes and seven transition metal ions. A further aspect of the present invention relates to a method of recording information onto the optical information recording medium and a novel azo metal complex dye.

1. An optical information recording medium comprising a recording layer on a surface of a support, wherein
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, and the azo metal complex dye is a complex of six azo dyes and seven transition metal ions, wherein the multiple transition metal ions contained in a single molecule of the azo metal complex dye may be mutually identical or different, and the multiple azo dyes contained in a single molecule of the azo metal complex dye may be mutually identical or different.
