Magnetic recording medium

摘要

The present invention aims to provide a particulate magnetic recording medium showing a high C/N in high-density magnetic recording (especially using an MR head for reproducing). Herein disclosed is a magnetic recording medium comprising a lower layer containing a nonmagnetic powder and a binder provided on a nonmagnetic flexible substrate and a magnetic layer containing a ferromagnetic powder and a binder provided thereon wherein said magnetic layer has an average thickness d of 0.01-0.1 mum, the ferromagnetic powder contained in said magnetic layer is an acicular ferromagnetic alloy powder having an average major axis length of 0.1 mum or less and a as of 120 A.m2/kg (120 emu/g) or less, the nonmagnetic powder contained in said lower layer is an acicular inorganic powder having an average major axis length of 0.15 mum or less, and said ferromagnetic powder has an aspect ratio equal to or smaller than the aspect ratio of said acicular inorganic powder.
