ABSTRACT:
A magnetic recording medium includes a first magnetic layer, a second magnetic layer, and a non-magnetic coupling layer provided between the first and second magnetic layers so that the first and second magnetic layers are exchange-coupled and the magnetizations of the first and second magnetic layers are antiparallel. The first magnetic layer has an exchange coupling field Hex1which is larger than the respective coercivities Hc1and Hc2of the first and second magnetic layers.
