PURPOSE: A magnetic recording medium is provided to prevent calendar roll contamination while producing, to prevent adhesion in a product, and to improve traveling duration and magnetic characteristic. CONSTITUTION: A magnetic paint formed by magnetic body, binder, lubricant, dispersing agent, and solvent is sprayed on a polyester film. Herein, 1.4-2.5wt% of surface processing agent including silicon, aluminum, and zinc is processed on oxidized steel. Herein, amount of silicon is 0.4-1.5wt% for reducing generation of condensate. Specific surface of the oxidized steel is over 26m2/g while having sinking rate of 6-10. Moreover, switching field distribution of the steel is 0.45-0.48. After spraying aqueous solution of silicon, aluminum, and zinc on the magnetic body surface, moisture is eliminated by dehydrating reaction.
