Abstract :
A novel magnetic printing technique designed for perpendicular hard-disk media using a lithographically formed master disk was satisfactorily demonstrated. In this paper, optimum conditions for the magnetic printing process are discussed by analyzing the waveforms of signals experimentally retrieved from the printed media and by numerical simulation using a finite element method.
