摘要

An optical recording medium on which information can be recorded by irradiation with a laser beam comprises (a) a substrate (l) and (b) a recording layer (3) which contains, based on the composition of the layer, from 35 to 94.9 atomic % of Te, from 5 to 25 atomic % of Se and from 0.l to 40 atomic % of F, and which has been produced by reactive sputtering, said Se being derived from selenium fluoride and a sputtering target of Te or a sputtering target comprising Te-Se-alloy. r
