The magnetization distribution in the patterned magnetic layer of master media and soft underlayer (SUL) resulting from perpendicular magnetic duplication utilizing the bit printing method was calculated by using micromagnetic simulation. As a result, it was found that the magnetizations of the magnetic layer of the master form a vortex structure. The magnetization distributions of the magnetic layer of the master and the SUL do not depend on the saturation magnetization and thickness of the SUL, but only on the duplication field. The peak-to-peak value of the recording field and the recording field gradient at the edge of the magnetic pattern of the master are almost independent of the saturation magnetization and thickness of the SUL. However, these values decrease slightly when the SUL thickness is reduced by less than 10 nm and the distance between master and SUL is increased.
