摘要:
A magnetic recording medium has magnetic patterns formed of a patterned ferromagnetic layer, and a non-magnetic layer including a component of the ferromagnetic layer and separating the magnetic patterns, in which a thickness “a” of the non-magnetic layer and a thickness “b” of the magnetic patterns satisfy a relationship of: a
