Abstract: A magnetic recording medium obtained by forming a Si-N-O system film on a magnetic recording layer with a perpendicular axis of easy magnetization. The magnetic recording layer is a metallic magnetic film such as a Co-Cr system alloy film. The oxygen content in the Si-N-0 system film is selected preferably to show a maximum absorption of infrared radiation in the range above 830cm ' and below 1100cm 1 of 1/λ (λ is the wavelength of the infrared radiation). Through formation of the Si-N-0 system film, the magnetic recording medium can satisfy simultaneously both the durability and the perpendicular magnetic recording chracteristics.

Abstract: A perpendicular magnetization film of iron-chromium alloy having an easy magnetization axis perpendicular to a plane of substrate, and the preparation thereof. The perpendicular magnetization film provides a dominant peak corresponding to a lattice constant of 2.07 to 2.08 A in X-ray diffraction spectrum, and possesses a large saturation magnetization of more than 100 emu/cm 3 . The perpendicular thin film can be prepared by depositing iron and chromium on the substrate under vacuum or an atmosphere of argon gas at a low pressure.
