| 中文摘要 | sb-bi alloy films are proposed as a new kind of super-resolution mask layer with low readout threshold power. using the sb-bi alloy film as a mask layer and sin as a protective layer in a read-only memory disc, the super-resolution pits with diameters of 380 nm are read out by a dynamic setup, the laser wavelength is 780 nm and the numerical aperture of pickup lens is 0.45. the effects of the sb-bi thin film thickness, laser readout power and disc rotating velocity on the readout signal are investigated. the results show that the threshold laser power of super-resolution readout of the sb-bi mask layer is about 0.5 mw, and the corresponding carrier-to-noise ratio is about 20 db at the film thickness of 50 nm. the super-resolution mechanism of the sb-bi alloy mask layer is discussed based on its temperature dependence of reflection. |
