ABSTRACT:
Antimony-tin alloys including a third element are useful for phase change optical recording. Some preferred alloys have a higher amorphous to crystalline transition temperature and thus, amorphous areas are stable for longer periods. Other preferred alloys exhibit improved CNR or lower noise or other improved performance characteristics.
