Abstract

PURPOSE: To improve a wear life characteristic without adhesion of a magnetic head by adding tetrafluoroethylene as a solid film lubricant to resin of the binder which is used for the magnetic recording medium.
CONSTITUTION: The composite where magnetic powder 3 of needle-shaped iron oxide, etc., binder 4 such as phenol and epoxy resin, and solid film lubricant 5 of tetrafluoroethylene are mixed is applied onto anode processing layer 2 on aluminum substrate 1 and is baked to form a magnetic recording medium. As a result, a magnetic recording medium can be obtained where over coat of a lubricant is not required and smoothness of the surface form and the life time are improved.
