Abstract

Phase change optical recording disks using have been found to demonstrate long thermal stability of the amorphous recording marks. The thermal analysis of Ag-Sb-Te material was studied using DTA and structural analysis of the material were studied by x-ray diffraction, SEM and TEM respectively. The films were studied for both the cases: before and after annealing and it was concluded that the alloy could be used as a phase change optical memory material.
