A perpendicular magnetic recording layer (RL) structure has multiple granular ferromagnetic layers (MAGs) that are separated by ferromagnetic exchange-coupling layers (ECLs) as interlayers between the MAGS. The ECLs provide effective intergranular exchange-coupling in the MAGs. Each MAG is sufficiently thick to support independent recording states that are thermally stable, and does not rely on the overall RL thickness for thermal stability. Each ECL has significant intralayer coupling of its grains. The material of the ECL may be a CoCr alloy, such as a CoCrPtB alloy. The Cr and B in the ECL create sam11 segregation regions or sub-grains in the ECL that are exchange-coupled on a length-scale smaller than the grain size. For each MAG grain, there exist a multitude of magnetic states corresponding to different transition positions in the ECL. These magnetic states are metastable and can be produced by a recording process, which in turn allows the RL structure to support a stable magnetization pattern with different magnetization states in adjacent MAGs. Thus, the magnetization states of the various MAGs may be fully correlated, but need not be fully correlated.
