Abstract
Two structures super-resolution near-field phase-change optical disks with masks Sb2 Te3 layer and a thermal shield layer in front of the mask layer on Blu-ray substrates were studied theoretically and experimentally. Optical simulation was conducted and the modulation transfer function (MTF) was calculated. MTF calculation results has revealed that the super-RENS optical disk exhibited the maximum response when nearly half of the laser spot was covered by the mask. The thermal simulation was used to find the optimum condition meaning that half of the laser beam is covered by the aperture on the mask layer. The recording signal and thermal stability on different structures were measured and analyzed. The simulation results are in good agreement with the experiment results.
