Claims (2)

소재필름⑾ 위에 자성층⑿을 증착하고 주행의 안정성을 위한 제1보호층⒀을 도포형성한 자기 기록매체에 있어서, 제1보호층⒀ 위에 산소가스를 포함한 강자성 금속을 증착하여 표면에 산화막을 구비한 제2보호층⒁을 형성한 것을 특징으로 하는 자기기록매체.In a magnetic recording medium in which a magnetic layer ⑾ is deposited on a material film 도포 and a first protective layer 도포 is coated and formed for driving stability, a ferromagnetic metal containing oxygen gas is deposited on the first protective layer 한 and an oxide film is provided on the surface. And a second protective layer 보호. 진공조내부에서 소재필름 위에 자성층을 증착하고, 그 자성층 위에 보호층을 도포형성하는 제조방법에 있어서, 자성층을 증착형성하는 중에 진공조내부에 6×10-5Torr 정도의 산소가스를 포함시켜 표면에 산화막을 구비한 자성층을 형성하고, 그 위에 고분자화합물등을 도포하여 약 300Å 이하의 제1보호층⒀을 형성하며, 그 제1보호층⒀ 위에 5×10-4Torr 정도의 산소가스를 포함한 Fe, Co, Ni 등의 강자성 금속을 증착함으로써 표면에 산화막을 구비한 제2보호층⒁을 형성하는 것을 특징으로 하는 자기기록매체의 제조방법.In the manufacturing method of depositing a magnetic layer on a material film in a vacuum chamber and applying a protective layer on the magnetic layer, the surface of the vacuum layer by including oxygen gas of about 6 × 10 -5 Torr in the vacuum chamber is formed. A magnetic layer having an oxide film was formed thereon, and a polymer compound or the like was applied thereon to form a first protective layer ⒀ of about 300 GPa or less, and containing oxygen gas of about 5 × 10 -4 Torr on the first protective layer VII. A method of manufacturing a magnetic recording medium, comprising forming a second protective layer 한 having an oxide film on a surface thereof by depositing ferromagnetic metals such as Fe, Co, and Ni. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
