MAGNETISM RECORD MEDIUM USING FEPT-B AND METHOD FOR MANUFACTURING THEREOF

摘要

A magnetism record medium using an FePt-B thin film and a method for manufacturing the same are provided to secure high coercivity and corrosion resistance of a magnetism record medium by adding Boron to an FePt alloy thin film. A magnetism record medium comprises an information recording unit for recording information, and an information storage unit for automatically storing the information recorded by the information recording unit. The information storage unit is made with an FePt-B thin film of an isotropic crystal structure formed by depositing Fe, Pt, and Born simultaneously so that the volume percent of the Boron is 33% and heat-treating at the temperature of 500~600°C.
