Abstract

A magnetic recording medium is constructed to include at least one exchange layer structure and a magnetic layer provided on the exchange layer structure, where the exchange layer structure includes a ferromagnetic layer and a non-magnetic coupling layer provided on the ferromagnetic layer, and a magnetic bonding layer provided between the ferromagnetic layer and the non-magnetic coupling layer and/or between the non-magnetic coupling layer and the magnetic layer, wherein the magnetic bonding layer has a magnetization direction parallel to the ferromagnetic layer and the magnetic layer.
