Abstract

In the patterned master magnetic contact duplication technique, the spacing between master and slave media seriously affects the duplication characteristics. When a slave medium with coercive squareness S^* of 0.43 was duplicated by using a master medium with a pattern width L of 2.5 μm and a magnetic layer thickness of 1 μm, it was found from experiments and simulation that the spacing loss factor K is about 30 dB. The reason for this small value is that the recording demagnetization in the duplication process is very weak. It is shown by simulation that a higher S^* value in slave media is advantageous for the patterned master magnetic contact duplication.
