摘要


藍光儲存媒體將成為下世代儲存媒體中最受矚目的焦點,藉由軌距縮短,並且使用405nm短波長的藍光雷射進行記錄讀取的工作提高光碟記錄密度。在本篇研究中針對可複寫式藍光光碟記錄層材料進行研究與探討,在GeSb-Sb2Te3擬二元合金當中添加適量的Bi,取代Sb提高結晶速度,並針對該添加不同含量Bi記錄材料的熱性質、光學性質、顯微組織、結晶構造、與製成碟片後燒入讀寫之品質進行討論。

Blue light storage media will become the most attractive focus in next generation of optical memory. Narrower track pitch, and shortened 405nm wavelength blue light laser have been utilized to increase the storage density. In this study, the blue light rewritable recording material will be discussed. Through doping small amount of Bismuth to substitute Antimony, the crystallization of speed can be accelerated in the pseudo-binary GeSb-Sb2Te3 alloy film. The thermal properties, optical characteristics, microstructure, crystal structure, and writing signal performance of blue laser disc made by Bi-added phase change materials will be discussed with various additions of Bi.
