Abstract :
A novel magnetic printing technique with a lithographically patterned master disk, which writes servo patterns onto a magnetic medium (slave disk), has been proposed. We discuss optimum conditions of the magnetic printing process by analyzing waveforms of signals experimentally retrieved from a hard disk drive medium. The waveforms observed at different dc magnetic fields applied to the master and slave disks during the printing process are well explained by computer simulation using a finite element method
