ABSTRACT:
Optical recording films made from alloys of antimony-tin and a third element exhibit improved properties when formed in a sputtering atmosphere containing a mixture of inert and organic gases. The amount of organic gas in the sputtering atmosphere is controlled. Improvements include higher amorphous to crystalline transition temperature and greater stability of the recorded and unrecorded film.
