Abstract

A magnetic recording medium is disclosed, comprising a flexible non-magnetic medium having on at least one surface thereof a magnetic layer comprising a ferromagnetic powder dispersed in a binder, wherein the heights and the existing densities of the abrasive projections and the non-abrasive projections on the surface of the magnetic layer are defined in the specific ranges. The magnetic recording medium are excellent in the electromagnetic characteristics, the magnetic head abrasion resistance, and the running durability.
