Patterned perpendicular magnetic recording medium with exchange coupled recording layer structure and magnetic recording system using the medium

A patterned perpendicular magnetic recording medium has discrete magnetic islands, each of which has a recording layer (RL) structure that comprises two exchange-coupled ferromagnetic layers. The RL structure may be an "exchange-spring" RL structure with an upper ferromagnetic layer (MAG2)...
