Abstract:
Disclosed herein is a super resolution optical disc. The super resolution optical disc comprises dielectric layers, and a mask layer formed between the dielectric layers, in which the mask layer is constructed as a complex mask layer comprising a metallic oxide (MOx) or metallic nitride (MNy), and a metallic thin film formed thereon. A size of the cavities and an amount of metallic particles in cavities created by illumination of recording laser can be controlled to increase a level of a reproduction signal for recording marks and to enhance the quality of the reproduction signal.
