Abstract
PURPOSE: To increase the wearing properties by mixing th perphloro alkyl polyether and the metallic salt of fatty acid into the magnetic layer as the lubricant.
CONSTITUTION: The lubricant featuring, for example,70:30W99.5:0.5 weight ratio between the perphloro alkyl polyether and the metallic salt of fatty acid is mixed into the magnetic layer composed of the magnetic powder and the binding agent which is provided on the substrate for the magnetic recording medium such as the magnetic tape or the like. The wearing properties can be enhanced more by using the nonmagnetic powder featuring the Mohs' hardness of over 6 together. The quantity of the lubricant to be used is set preferably to 1W25 part by weight to 100 of the magnetic powder along with the nonmagnetic powder set to 0.5W5wt% to the magnetic powder respectively.
