Abstract
PURPOSE:To obtain an easily manufacturable optical information recording medium having superior recording performance and stability, by holding a specific compound on a substrate. CONSTITUTION:In an optical information recording medium for recording, regenerating, or erasing with a laser beam, a compound shown by a general formula I is held on a substrate. In the formula, R<1>, R<2> independently represent alkyl group or aryl group, Z represents an atom group for forming an aromatic ring, L represents a linking group for forming a carbocyanine, and X represents perfluoroalkane sulfonic ion. In this manner, a recording layer of the optical information recording medium capable of keeping sufficient recording properties for a long term and superior in stability can be formed. Thus, the cyanine dye-containing optical information recording medium which is free from the risk of explosion and enhanced in solubility in an organic solvent can be obtained. In the optical recording medium, information is recorded by a method in which; a spot-form high energy beam such as a laser is irradiated on the recording layer, the light absorbed in the recording layer is converted to a heat, and a pit is formed on the recording layer. The information is read by detecting a change in quantity of reflected light or transmitted light at a pit part and at a pit-free part.
