A magnetic recording medium is disclosed, comprising a nonmagnetic support having provided on a first side of the support a magnetic layer containing a ferromagnetic powder and a binder, the ferromagnetic powder is a ferromagnetic metal powder having a water-soluble calcium content of 100 ppm or less, and the ratio of widthwise stiffness (TD) to lengthwise stiffness (MD) of the magnetic recording medium is in the range of from 0.65 to 1.00. In a preferred embodiment, the magnetic layer contains a saturated aliphatic acid having 14 to 24 carbon atoms, the magnetic layer has a dry thickness of from 0.5 to 3.5 mu m, the nonmagnetic support has a thickness of from 8 to 11 mu m, and the magnetic recording medium further comprises a backing layer having a dry thickness of from 0.1 to 1.0 mu m. |
