<P>PROBLEM TO BE SOLVED: To provide an optical recording medium for high-density recording suited for the formation of a small record mark corresponding to a record density of at least 100 Gbits/in<SP>2</SP>. <P>SOLUTION: On a substrate 11, a titanium oxide layer or a titanium oxynitride layer 12 and a carbon layer 13 are adjacently formed as a recording layer. The recording layer is irradiated with near-field light having a wavelength different from a reproduction wavelength for recording, and reproduction is made by near-field light having a wavelength where the recording layer does not deteriorate. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
