Abstract

PURPOSE:To obtain a surface lubricious film which is uniform, extremely thin and free from head sticking, by improving the effect of a wiping-off treatment, by improving the flowability of a lubricant by heating the surface of a magnetic disk in wiping off the surface with the lubricant. CONSTITUTION:On a magnetic disc 1 formed by providing a gamma-Fe2O3 magnetic film, etc., on an aluminum substrate, a dilute lubricant is applied and while the disk is heated by an infrared-ray heater 2 up to 150-170 deg.C surface temperature, the surface is wiped off with a rotary pad 3 to which paper containing no fat or oil is stuck.
