Abstract
A magnetic contact duplication technique using lithographically patterned master meida is investigated in order to write a servo signal on hard disks and floppy disks at a high speed and alow cost. In this technique, the coercivity of the master media is low, and dc magnetic field is appied to a slave medium contacted with the master one. A computer simulation using finite element method shows that the pattern of the master medium can be duplicated on a slave one. The possibility of duplication by using this technique is confirmed from experimetal results in which a Bitter pattern of a duplicated slave medium is clearly observed.
