Title: Magnetic recording medium
Inventor: KOYAMA AKIO
IPC: H01F10/00
Filed: 1979-09-25
Abstract: PURPOSE: To improve wear resistance and running property by forming a nonmagnetic thin film of specific hardness or more on a polymer film whose surface is roughened, by providing on it a metal magnetic layer to a thickness less than the polymer surface roughness, and by partially exposing the nonmagnetic layer.  
     CONSTITUTION: On base 1 obtained by heat-treating a polyester film in an NaOH solution to a surface roughness of approximately 0.05Wlμ, nonmagnetic thin film 2 of 6 or more in mohs hardness composed of a metal such as Cr and Si, oxide such as Al 2 O 3 , Sic, TiN, etc., is vapor-deposited under vacuum to a thickness of 0.01W 0.1μ. Next, magnetic layer 3 of Co, Ni, Fe, or their alloy is vapor-deposited under vacuum to approximate 0.04W0.9μ. Lastly, surface work or polishing is done with a heat calendar, knife edge, etc., to expose the projection of nonmagnetic layer 2 of wear resistance partially. Thus, a magnetic tape of endurance can be obtained which is nearly free from output fluctuations for a long period.
