Abstract:
A method for producing an optical recording medium, comprising the steps of:forming on a transparent substrate a recording layer consisting essentially of at least one antimony base thin film and at least one reactive thin film and wherein said antimony base thin film and said reactive thin film are disposed in close contact;forming said antimony base thin film by depositing an Sb base material containing at least 95 at % of antimony to a thickness of at least 70 .ANG.;forming said reactive thin film by depositing an In--Ag--Te base material containing indium, silver, tellurium and antimony as major components,mixing antimony with said antimony thin film base material and said reactive thin film to form recording material; andirradiating recording light on the mixed phase change recording material to form recording marks thereon.
