Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic recording medium which can realize a short recording wavelength and a high recording density. SOLUTION: In this magnetic recording medium, a magnetic layer where magnetic powder is dispersed in a resin binder is provided on the surface of a coating film of a biaxially oriented polyester film (ILC film) which has the coating layer provided in a film formation process, and the coating film satisfies a prescribed solvent resistance characteristic, and a thickness (t)(μm) of the coating layer, a thickness tM (μm) of the magnetic layer, and a filler particle size (d) of the film layer on the magnetic layer coating side satisfy formulas 0.05
