MAKING METHOD OF OPTICAL MAGNETO RECORDING MEDIUM

摘要

(1) forming a first dielectric layer on a substrate with a reactive sputtering method; (2) sequentially forming a record layer and a second dielectric layer on the first dielectric layer; and (3) forming a refractive layer on the second dielectric layer, depositing a DLC on the refractive layer and forming a protective layer being 0.1 to 1μm in thickness with a plasma method.
