Abstract
There is disclosed an antimony, tin and indium alloy which contains an additional element. The additional element is selected from the group consisting of titanium, aluminum, magnesium, manganese, silver, bismuth, germanium, lead, tellurium, gold, zinc, copper, palladium, nickel, iron, cobalt, and cadmium. The additional element substantially reduces arcing during the sputtering process used to make optical recording layers from the alloy.
