Abstract
Disclosed is a multi-layer super resolution optical disc. In the multi-layer super resolution optical disc, at least two recording layers, each of which comprises at least two mask layers and impact absorption layers formed between the mask layers, are laminated, and intermediate layers of polymer thermo-set by ultraviolet rays are formed between the recording layers. Accordingly, jitter characteristics for recording marks are improved, and recording density is enhanced.
