Paper Abstract

Phase change optical recording disks using chalcogenide alloy Ag-Sb-Te have been found to demonstrate long thermal stability of the amorphous recording marks. The crystallization process and nature of Ag-Sb-Te material were studied using Differential Thermal Analysis (DTA) and X Ray Diffraction (XRD) respectively. The films were studied for both the cases: before and after annealing and it was concluded that the alloy (Ag-Gb-Te) can be used as a phase change optical memory material.
