Magnetic recording media and manufacturing method thereof.

摘要

Magnetic recording media characterized by comprising composite polymer films, which are formed of flat surfaced polymer films and both inorganic particles and organic particles dispersed and attached on the surface of said polymer films, and magnetic films disposed over said particles which are attached on the surface of said composite polymer films, and the manufacturing method thereof, contributing to satisfying all the performance requirements made of magnetic recording media in a balanced manner for electromagnetic conversion characteristics, a picture drop out performance, and running characteristics of magnetic recording tapes, and at the same time maintaining the foregoing excellent performances even after repeated use of the magnetic recording tapes with resultant realization of excellent long-term reliability.
