Title:
MAGNETIC RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPH06301968
Kind Code:
A
Abstract:
PURPOSE: To obtain a magnetic recording medium having a ferromagnetic metal layer on a nonmagnetic substrate and having a protective layer thereon which shows excellent wear resistance and corrosion resistance by constituting the protective layer of a material expressed by specified formula.
CONSTITUTION: This magnetic recording medium has at least one ferromagnetic metal layer on a nonmagnetic substrate and has a protective layer on the metal layer. The protective layer comprises a compd. expressed by formula X-(CH2)n-(CF2)m-Y. In the formula, X is H2O3P, HO3 S, NaO3SS, HS or H3C-SO3, Y is CH3 or CF3, n is an integer 3 to 11, and m is an integer 0 to 7. Thereby, the obtd. medium has excellent wear resistance and corrosion resistance.
