A second magnetic layer at a side farther than the nonmagnetic intermediate layer to the substrate is constituted of an alloy film which contains Pt, Cr and B and is consisting essentially of Co. Magnetization directions of the first magnetic layer and the second magnetic layer are in antiparallel to each other in a state where no applied magnetic field exists. Accordingly the magnetic recording medium of this invention has an effect to reduce the medium noise while maintaining thermal stability of recording bits in comparison with conventional magnetic recording media. By using the magnetic recording medium of this invention, a magnetic storage device which can record/reproduce high density information and has high reliability can be provided.
