DEPOSITION METHOD OF A MAGNETIC RECORD MEDIUM

摘要

A depositing method of a magnetic record medium is characterized by depositing metallic material with an arbitrary angle on the non magnetic supporting material transported to the winding reel from the supplying reel circling around a metal can installed in a vacuum chamber. The magnetic recording medium produced by this method has high corrosion resistance and high wear resistance caused by the fact that the thin film itself is made up of oxide.
