Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic recording medium excellent in electromagnetic conversion, which has a flat surface with high output and excellent C/N. SOLUTION: In a magnetic recording medium which has at least a magnetic layer containing ferromagnetic powder and binder on a support base, this magnetic recording medium is featured in that the closed pore volume Vs in the coating is 0.25 or less of the sum Vos of the open pore volume Vo and the closed pore volume Vs.
