PROBLEM TO BE SOLVED: To provide an optical recording medium which can efficiently implement the additional writing of a data part by a high frequency wobble format which can be produced more simply than a land pre-pit format which is used in DVD-R, and which uses approximately the same format with that of mass-produced CD-R and DC-RW. SOLUTION: In the optical recording medium in which an organic coloring matter recording layer is formed on a substrate, a wobble 4T-96T in frequency is provided, and the organic coloring matter recording layer is salt forming coloring matter of cyanine coloring matter and azo metal chelate coloring matter. |
