A method of producing a magnetic recording medium includes forming a underlayer on a base, and successively forming, on the underlayer, a first magnetic layer, a nonmagnetic coupling layer and a second magnetic layer. The first and second magnetic layers are exchange-coupled via the nonmagnetic coupling layer and have antiparallel magnetizations in a state where no external magnetic field is applied on the magnetic recording medium. The underlayer is made of Cr or a Cr alloy having a bcc crystal structure within an atmosphere including nitrogen gas.
