Abstract

PURPOSE: To obtain a magnetic recording medium having a magnetic layer which excels int the durability with a small surface electric resistance, by adding the perfluoroalkyl-phosphoric ester into the magnetic layer.
CONSTITUTION: The perfluoroalkyl-phosphoric ester is added into the magnetic layer in a range of 0.1W10wt% based on the magnetic powder. In this case, the perfluoroalkyl-phosphoric ester is dissolved into the proper solvent of the isopropyl alcohol or the like. And 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-phosphoric ester is kneaded together with the magnetic powder and the binder to form the magnetic layer.
