A super-resolution recording medium is provided to solve a problem that a CNR(Carrier to Noise Ratio) value rapidly decreases at more than certain power while increasing as reproduction power increases during reproduction of the recording medium, thereby improving margins for the reproduction power. A substrate(510) is equipped. A super-resolution recording layer(530) leads a super-resolution phenomenon which enables marks which are less than resolution size to be reproduced by a super-resolution aperture area where optical characteristic changes or temperature dispersive changes occur among areas of an incident optical spot. A super-resolution aperture control layer(550) regularly maintains the super-resolution aperture area.
