Abstract

PURPOSE: To improve the bonding property and wear resistance of a metal magnetic layer by forming on a supporter a nonmagnetic polymer layer that includes lubricant powder and has partial surface projections.
CONSTITUTION: On supporter 1, base material layer 2 of a nonmagnetic polymer layer is formed which contains nonmagnetic and solid lubricant powder such as molybdenum disulfide of ≤3μ in mean grain size. This is processed by a heat calendar roll, etc., chased with a pattern to form projections of not less than the thickness of a magentic film to be formed next. On this base material layer 2, metal magnetic layer 3 of Co, Ni, etc., is provided by plating to a thickness of about 0.05W0.2μ. Next, surface work is carried out to expose base material layer 2 partially on the surface. Consequently, a magnetic recording medium superior in wear resistance and running property can be obtained.
