Magnetic recording medium comprising a magnetic layer and a non-magnetic support each having specified elastic modulus valves

摘要

Disclosed is a magnetic recording medium which is improved in electromagnetic conversion and running durability which includes a magnetic layer containing a ferromagnetic powder dispersed in a binder on a non-magnetic support, wherein the sum of the elastic modulus in a longer direction of the non-magnetic support and the elastic modulus in a width direction of the non-magnetic support is 1,250 kg/mm2 or more; an elastic modulus in a longer direction of the magnetic layer is 0.6 to 3.0 times as much as the elastic modulus in the longer direction of the non-magnetic support; and an elastic modulus in a width direction of the magnetic layer is 0.4 to 2.0 times as much as the elastic modulus in the width direction of the non-magnetic support.
