ABSTRACT:
A super-resolution optical recording medium has at least a recording layer and a super resolution layer on a substrate. A recording mark with the size of a resolution limit or less and a space with the size of the resolution limit or less are formed in the super-resolution optical recording medium by adjusting the intensity of a laser for recording or an emission pattern of the laser for recording such that at least the recoding mark with the size of the resolution limit or less out of recording marks in a modulation code is formed into a concave section with respect to a not-recorded section.
