ABSTRACT:
Optical recording films made from alloys of antimony-tin and a third element exhibit improved properties when formed in an atmosphere containing oxygen. The amount of oxygen in the sputtering environment is controlled. Improvements include higher amorphous to crystalline transition temperature, improved carrier to noise ratio (CNR) and greater stability of the recorded film.
