Magnetic recording medium

Abstract

A magnetic recording medium having a magnetic layer formed by coating a non-magnetic support member with a magnetic coating material mainly composed of ferromagnetic iron alloy powder and a binding material, wherein the magnetic coating material includes ferromagnetic iron alloy powder containing Co by 6 to 30 atom %, Y by 1 to 6 atom % and Al by 10 to 15 atom % with respect to Fe and having an average major axis length of 0.06 .mu.m to 0.20 .mu.m, polyvalent carboxylic acid having a molecular weight of 300 or less or an anhydride of the polyvalent carboxylic acid, a binding material, and a lubricant, and the maxim diameter of pores in the magnetic layer is 10 nm to 30 nm.
