<p>An optical information recording medium, recording/reproducing method thereof, and recording/reproducing apparatus with superior signal quality for high-density recording that has high storage reliability is provided. The optical information recording medium of the present invention has at least one information layer having a recording layer and a dielectric layer in order on a transparent substrate. The dielectric layer is comprised of greater than or equal to 50 molecule percent and less than or equal to 98 molecule percent of Zn-O, and greater than or equal to 2 molecule percent to less than or equal to 50 molecule percent of one or more compounds selected from the group consisting of Y-O, Ce-O, Nb-O, Ta-O, Cr-O and Mo-O.</p> |
