Abstract

PURPOSE: To obtain a magnetic recording medium having a magnetic layer which excels in the durability with a small surface electric resistance, by adding the perfluoroalkyl-ethylene oxide adduct into the magnetic layer.
CONSTITUTION: A perfluoroalkyl-ethylene oxide adduct is added into the magnetic layer in a range of 0.1W10wt% based on the magnetic powder. In this case, the perfluoroalkyl-ethylene oxide adduct is dissolved into the proper solvent of the isopropyl alcohol or the like. Then the solution thus obtained is coated or sprayed to the magnetic layer which is formed previously, or reversely the magnetic layer is immersed into the solution. Otherwise the perfluoroalkyl-ethylene oxide adduct is kneaded together with the magnetic powder and the binder to form the magnetic layer.
