Abstract

PURPOSE:To improve the corrosion-proof performance, by irradiating electron rays on a ferromagnetic substance metal thin film under oxygen atmosphere. CONSTITUTION:An electron generated from an electron generating source 2 provided at the upper part of a vacuum vessel 1 is accelerated with a metal thin film 3 to which a positive potential is applied, and collided on a ferromagnetic substance thin film 7 of a magnetic recording medium 5 located to be moved toward the arrow A in a space 8 sectioned with the metallic thin film 3 and a shield wall 4 under oxygen atmosphere with the oxygen 10 introduced from a nozzle 9.
