Paper Abstract

The non-linearity of the super-RENS mask can be used in optical data storage, which can greatly increase the disk’s density. Experiment is carried on the traditional mastering system with modification. We adopt the SiN/Sb/SiN multiplayer as the mask to insert the optical mask. For 413nm semiconductor laser and lens with NA=0.9, the diffraction limit is 200nm theoretically. Mark-120nm much smaller than that size is generated in the experiment. The thickness of Sb in the mask layers has much effect on the mastering signal intensity. For different power, we should control the thickness of Sb film. The experiments results show that the super-RENS mask can actually reduce the size of the mark obviously and realize the high density optical storage.
