Abstract
A super-resolution optical information recording medium comprises a super-resolution layer and a recording layer which are laminated on a support substrate, wherein the super-resolution layer is provided with properties consisting of a first state to maintain a solid phase against irradiation of a laser beams, and a second state to become a liquid layer state against irradiation of a laser beam onto a recording mark on the recording layer to thereby change an optical constant. The optical constant is determined so that a ratio of a super-resolution signal intensity obtained at a second state region against a background light interference intensity obtained at a first state region is at least 1.8, and a ratio of the super-resolution signal intensity obtained at the second state region against a disk noise intensity obtained at first and second state regions is at least 0.16.
