Magnetic recording medium

Abstract

A magnetic recording medium which is capable of improving durability and reliability while satisfactory electromagnetic conversion characteristics are being maintained, the magnetic recording medium incorporating a non-magnetic support member; and a magnetic layer formed on the non-magnetic support member and mainly composed of magnetic powder and a binder and having a two-layer structure composed of a first magnetic layer and a second magnetic layer, wherein Young's modulus of the first magnetic layer is 140×105 N/m2 to 160×105 N/m2 and Young's modulus of the second magnetic layer is 45×105 N/m2 to 50×105 N/m2. The specific surface area of the magnetic powder for use in the first magnetic layer is 42 m2/g to 46 m2/g and the specific surface area of the magnetic powder for use in the second magnetic layer is 32 m2/g to 35 m2/g.
