| Abstract(in English) | The magnetic duplication technique using patterned master media is a promising means of writing servo signals onto hard disks at high speed and low cost. It is expected that the direction of the applied magnetic field in the duplication process significantly influences the duplication characteristics. The objective of this paper is to clarify the influence of the oblique magnetic field out of the master plane. Experiments showed that the reproduced wave form from a slave duplicated with an oblique field is asymmetric near both edges of the protrusion of the master. The asymmetric wave form is improved by increasing the field, but the duplication characteristics duplicated with an oblique field are still inferior to those with an in-plane field. Computer simulation of the magnetization distribution of the slave duplicated with an oblique field shows that the distribution is asymmetric near both edges of the protrusion of the master, coinciding with the experimental results. |
