Abstract
PURPOSE: To form a thin film type magnetic recording medium of superior lubricity and abrasion resistance by poviding a resin thin film of a specific thickness on the ferromagnetic thin film formed on a substrate.
CONSTITUTION: A resin thin film 6 having the thickness (d) below 0.5 times the maximum value (Rmax) of the surface roughness of a substrate 2 is provided on the ferromagnetic material thin film 3 of about 0.1 to 0.3μ in thickness formed on the substrate 2 such as of polyester film, polyimide film or other. The provision of the resin thin film 6 by giving such a specific thickness enables the resistance between the medium and a head 7 to be reduced.
