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

Phase change materials based on addition of ceramic material (ZnS–SiO 2) into antimony–indium–tin (Sb 100− x− y Sn x In y ) 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–SiO 2 and the chemical composition of the parent Sb 100− x− y Sn x In y phase change material.
