Rewritable and initialization-free AgO/sub x/ type super-resolution optical recording medium

An initialization-free structure for the AgO/sub x/ super-resolution near-field structure (super-RENS) optical disk has been investigated, and results showed the improvement of the CNR. High reflectivity, better tracking and increasing of the CNR on the initialization-free AgOx super-resolution DVD disk and phase-change disk of AlTi/ZnS-SiO/sub 2//Sb/sub 2/Te/sub 3//Ge/sub 2/Sb/sub 2/Te/sub 5//Sb/sub 2/Te/sub 3//ZnS-SiO/sub 2//polycarbonate have successfully demonstrated the feasibility of this novel structure.
