ABSTRACT:
A magnetic recording media is manufactured which includes a composite polymer film, which is formed of a flat surfaced polymer film and both inorganic particles and organic particles dispersed on and attached to the surface of the polymer film, and a magnetic film disposed over the particles which are attached on the surface of said composite polymer film. The magnetic recording media satisfies the performance requirements of magnetic recording media in a balanced manner including electromagnetic conversion characteristics, picture drop out performance, and running characteristics of magnetic recording tapes, and at the same time maintaining the foregoing performance characteristics even after repeated use of the magnetic recording tapes.
