The optical information recording medium, which can record and reproduce information using semiconductor laser, is characterized in that information is recorded by the reaction that separates the recording medium into halogen atom and gold with the temperature increase, while information is reproduced by the difference of reflectivity of separated part and non-separated part. The halogen atom for halogenated gold compound is chosen from Cl, Br or I. The use of halogenated gold compound can simplify the manufacturing process of optical recording medium and prevent S/N reduction. |
