PROBLEM TO BE SOLVED: To provide a heat mode type optical information recording medium which can obtain high recording sensitivity even when visible laser beams are used besides near infrared laser beams and attain high reflectance, and a information recording method. SOLUTION: In a heat mode type optical record recording medium having a recording layer which can record information by the irradiation of laser beams, the recording layer contains a cyanine coloring matter compound expressed by a formula [DYE<+> ]n X<n-> (DYE<+> is a monovalent cyanine coloring matter cation, n is integer of 2 or more, X<n-> is n-valent anion), and a DVD-R type optical recording medium is irradiated with laser beams of 630-680nm wavelength to record information. |
