A magnetic recording medium production method which includes forming a lubricating layer over a stack including a substrate, a magnetic recording layer over the substrate, and a protective layer over the magnetic recording layer includes applying a first lubricant and a second lubricant to the stack; burnishing a surface of the stack with an abrasive; and removing the second lubricant over the stack. The application of the second lubricant is performed through dipping or spin coating. A dissolution amount of the second lubricant in a solvent for the second lubricant used in the dipping or the spin coating is more than a dissolution amount of the first lubricant in the solvent. The burnishing includes abrading the surface of the stack by pressing a tape containing the abrasive against the surface of the stack. The removal of the second lubricant includes irradiating the stack with ultraviolet radiation, or heating the stack.
