Disclosed is a super resolution optical disc. The super resolution optical
disc comprises at least two mask layers. In one embodiment, the super
resolution optical mask comprises a plurality of mask layers and impact
absorption layers between the mask layers, and may further comprise
diffusing prevention layers between the mask layer and the impact
absorption layer. In another embodiment, the super resolution optical
mask comprises a plurality of recording layers and dielectric layers
separating the recording layers, each of the recording layers including
two mask layers and an impact absorption layer between the mask layers or
including two mask layers, an impact absorption layer between the mask
layers, and diffusion preventing layers between the mask layer and the
impact absorption layer. Accordingly, recording marks have an enhanced
shape at an outer periphery of the marks, thereby enhancing the quality
of the reproduction signal and enabling high-density multi-level
recording.
