Development of phase change material for write once Blu-ray disc

Phase change materials based on addition of ceramic material (ZnS–SiO2) into antimony–indium–tin (Sb100−x−ySnxIny) have been considered as possible candidates for high density optical data recording. Chemical compositions of the alloys have been optimized in order to develop a new high density Blu-ray Recordable Low to High optical data format. The evaluation of electrical parameters of resultant product shows that the jitter depends on the percentage of ZnS–SiO2 and the chemical composition of the parent Sb100−x−ySnxIny phase change material.
