A magnetic recording medium comprising a non-magnetic substrate, and an oriented magnetic recording layer having a thickness of from about 0.025 micron to about 0.25 micron coated thereon including at least one non-sintered particulate magnetic metallic pigment having a coercivity of at least about 2000 Oersteds and an average particle length no greater than about 150 nanometers, and a binder system comprising from about 2 to about 10 parts by weight of a polyurethane resin, and from about 1 part to about 10 parts by weight of at least one lubricant selected from the group consisting of fatty acids and fatty acid esters, wherein the magnetic recording medium has a squareness of at least about 0.95 when measured at a field strength of 6000 Oe.
