A magnetic recording medium comprising a non-magnetic support and, formed thereon, a magnetic layer containing a binder and a magnetic powder having the surface mainly comprising carbon and/or iron carbide. The magnetic layer contains an organic dye compound having at least one polar group selected from hydroxyl, carboxyl, sulfo and salts thereof, and the binder contains an amino group and/or an ammonium salt group. This medium is improved in the dispersion of a magnetic coating and also in surface properties, magnetic characteristics, and electromagnetic transduction performance. |
