MANUFACTURING METHOD OF OPTICAL INFORMATIONRECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a recording medium having an excellent recording characteristic which makes it possible to preserve a pigment solution used for forming the film of the recording layer of an optical recording medium and the recovered pigment solution for a long time, and stabilizes the composition of the recording film. SOLUTION: When the optical recording medium having at least the recording layer containing the pigment and a metallic reflecting layer is prepared on a supporting substrate, the recording layer is obtained by dissolving the pigment in a solvent containing as a main component a hydrocarbon-based solvent whose concentration is controlled below a concentration at which a peroxide causes the oxidizing decomposition of the pigment contained in the recording layer, coating the supporting substrate with the obtained pigment solution and drying it to form the recording film.
