Abstract
Super-resolution near-field optical disk is one of the solutions to overcome diffraction limit and achieve high density optical recording. In this paper, a structure of super-resolution near-field phase-change optical disk with a thin thermal shield layer behind the recording layer is proposed. The optical disks with the new structure were studied theoretically and experimentally. Thermal simulation shows that the thermal shield layer can reduce the phase change layer temperature, thus improve the thermal stability of the disks. The disks with this structure were fabricated and characterized. The experiment results are in good agreement with the simulation results.
