The CNR value of recoding mark trains of 100nm can be achieved to 33dB.In the further studies, we change the layered structure of ZnOx-type near-field optical disk and optimize the write strategy of commercial optical disk driver. By the change of different thickness of dielectric spacer (ZnS-SiO2), the interaction between the ZnOx near-field active layer and phase-change material is studied. From the experimental results, the optimized layered structure can be obtained as DVD+RW\ ZnS-SiO2 (130nm)\ ZnOx (15nm)\ ZnS-SiO2 (60nm)\ Ge2Sb2Te5 (20nm)\ ZnS-SiO2 (20nm) with bonding.氧化鋅近場光碟片商用光碟測試機商業片三層片near-field optical diskZnOxCNRDDU-1000ITRI Commercial Disc Driver
