Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic recording medium wherein the packing ratio of magnetic powder in a magnetic layer can be heightened and thereby satisfactory long wavelength output characteristics can e obtained, and to provide a method for manufacturing the magnetic recoding medium. SOLUTION: The magnetic recording medium formed by successively laminating a nonmagnetic layer 3 formed by dispersing non-magnetic powder 3b in a nonmagnetic layer resin 3a and a magnetic layer 5 formed by dispersing magnetic powder 5b in a magnetic layer resin 5a on a nonmagnetic substrate 1 is characterized in that the glass transition temperature TgU of the magnetic layer resin 5a and the glass transition temperature TgL of the non-magnetic layer resin 3a satisfy the relation of TgU
