The formation of magnetic clusters and remanence coercivity in granular-type perpendicular recording media was discussed. The value of perpendicular anisotropy, was obtained from the value measured by torque magnetometry. It was found that the value of Dcluster could be determined by the strength of intergranular coupling, which was well supported by R/W performances.
