ABSTRACT:
An irradiation method of applying a light spot or a light pattern to an object with high resolution is performed by disposing, in close vicinity to the object, a light-absorbing contrast-increasing layer whose transmittance or reflectivity with respect to an incident light thereto increases as the intensity of the incident light or the exposure thereof to the incident light increases; and applying light to the object through the light-absorbing contrast-increasing layer. This method is applied to an optical information recording and reproducing method using an optical information recording medium including an optical information recording layer and an auxiliary layer whose transmittance or reflectance increases in a real time manner correspondingly to the energy of an incident light thereto.
