Paper Abstract

Super-resolution read-only optical disks using different mask materials and stack structures were prepared by using rf sputtering method, and then dynamic readout properties were measured, our results show that by using Si as the mask material the signal-to-noise ratio can reach about 35dB, and the density can be increased both in the linear direction and in the track direction, while by using AgInSbTe as the mask material the optimum signal-to-noise ratio is about 40dB, which is very close to the practical application level.
