Abstract:
1. An optical information recording medium comprising: a recording layer including a cured resin comprising an acid generator having a vaporizing temperature in a range of 140° C. to 400° C. and an acid-reactive compound, the cured resin adapted to absorb condensed recording light having a wavelength of approximately 350 to 600 nm for recording optical information such that upon exposure of the cured resin to a focal point of the condensed recording light, a temperature in a vicinity of the focal point of the condensed recording light increases so as to vaporize the vaporizing material, wherein the cured resin includes a cavity formed from vaporized material as a recording mark representing optical data formed in the vicinity of the focal point of the condensed recording light, and wherein the recording layer has properties of increasing a light absorption amount with respect to the wavelength of the condensed recording light by heating performed at a temperature of 120° C. or more.
