Crystallization Characteristics and Recording Mechanism of a-Si/Ni Bilayer and Its Potential for use in Write-Once Blue Ray Disk

Abstract

In this work, the crystallization characteristics and recording mechanism of a-Si/Ni bilayer recording film under thermal annealing and pulsed laser irradiation are investigated. The optical properties of the a-Si/Ni bilayer recording film before and after annealing were measured. In addition, the dynamic test was conducted to evaluate the potential of the a-Si/Ni bilayer for use in the write-once blue-ray disk
