Abstract

PURPOSE: To increase both the wearing properties and the non-wearing properties to the object by mixing the fluorine oil and the nonmagnetic powder featuring a fixed hardness into the magnetic layer.
CONSTITUTION: The nonmagnetic powder featuring the Mohs' hardness of over 6 plus the fluorine oil are mixed into the magnetic layer composed of the magnetic powder and the binding agent which is provided on the substrate of the polyester film and the like for the magnetic recording medium such as the magnetic tape or the like. The nonmagnetic powder features the average grain size of 0.5W2μ for Al2O3, SiO2, etc. and is used preferably in the amount of 0.5W5wt% to the magnetic powder, along with the quantity of the fluorine oil set to 0.5W20wt% to the magnetic powder respectively.
