| Abstract(in English) | The characteristics of magnetic contact duplication for perpendicular magnetic recording media are investigated by using the three-dimensional finite element method. In order to magnetically duplicate a servo signal on perpendicular recording media, there are two methods of applying a duplication magnetic field. One is method to apply a magnetic field in a direction perpendicular to the disk plane (bit printing, BP), and the other is to apply a field in the disk plane (edge printing, EP). The results of simulation show that in BP the duplication field dependence of the duplication performance has a maximum value near the coercivity of the slave, while EP has better duplication performance at higher duplication field. EP is more advantageous than BP for duplication of perpendicular magnetic recording media. |
