Abstract
PURPOSE: To improve resistance to wear and running property by partially exposing a base material layer for a nonmagnetic polymer layer including a solid lubricant by performing surface processing after providing the base material and metal magnetic layer on a supporter.
CONSTITUTION: On supporter 1, acoating of base material containing solid lubricant powder of ≤ about 3μ in mean grain size such as nonmagnetic molybdenum disulfide is applied with its surface roughness greater than the thickness of a magnetic layer and base material layer 2 is formed by drying. Next, metal magnetic layer 3 of Co, Ni, etc., is provided by plating to a thickness of about 0.05W2μ. Then, base material magnetic layer 2 is partially exposed on the surface by rolling or surface polishing. Consequently, a magnetic recording medium having excellent resistance to wear and running property without any influence on electromagnetic characteristics can be obtained.
