Abstract
PURPOSE:To improve running durability and weatherability by using a binder contg. polycarbonate polyurethane as a binder. CONSTITUTION:The binder is formed of the binder contg. the polycarbonate polyurethane. Namely, a magnetic layer formed by combining fine ferromagnetic powder of iron nitride and the binder contg. the polycarbonate polyurethane is provided on the surface of a nonmagnetic base. Fine powders of various forms contg. iron nitride which is a ferromagnetic material are usable as the fine ferromagnetic powder of iron nitride. The magnetic recording medium which is not degraded in the electromagnetic conversion characteristics even at and under a high temp. and high humidity and has the excellent traveling property and weatherability is thereby obtd.
