Abstract

PURPOSE:To improve the running stability and durability of a magnetic recording medium by improving the lubricity and wear resistance of a magnetic layer by making the magnetic layer contain a specific organic silicone compound. CONSTITUTION:A magnetic layer is made to contain an organic silicone compound which has two kind of modified groups: one has a superior affinity with a binder having a polar group, such as a hydroxyl-group containing hydrocarbon group, carboxyl group containing hydrocarbon group, amino group containing hydrocarbon group, and epoxy-group containing hydrocarbon group, in a principal chain, and the other has a superior affinity with a binder having none of polar groups, such as a hydrocarbon group and aryl hydrocarbon group.
