Abstract

PURPOSE: To obtain a magnetic recording medium having a small adsorbing force to the head and excellent wear resistance properties and the high surface lubricating properties, by impregnating the lubricant into the micropores on the coated film which is formed by coating the magnetic coating material and then giving a high- temperature baking.
CONSTITUTION: The magnetic coating material (mixture of magnetic powder, binder resin, thinner, etc.) is coated on the disk 2 and then baked at high temperatures of about 250W300°C. As a result, the coated film 1 can be obtained with formation of a number of micropores 3 having the diameters of about 0.3±0.1μm on the surface. Then the lubricant is coated on the film 1 and then heated up to about 15C or higher to ensure a uniform impregnation of the lubricant into the pores 3. As a result, a magnetic disk recording medium for magnetic disk device can be obtained with a betterment of the anti-CSS (contact start-stop) properties.
