Magnetization Distribution of Tb/in ^ Class Hard Disks Recorded With Bit Printing and Edge Printing

In this paper, printing characteristics for the bit printing and the edge printing were compared by micromagnetic simulation. As a result, servo signal can be clearly recorded using both printing methods, and printing field dependence of printing performance for each method is considerably different...

description	In this paper, printing characteristics for the bit printing and the edge printing were compared by micromagnetic simulation. As a result, servo signal can be clearly recorded using both printing methods, and printing field dependence of printing performance for each method is considerably different. The transition of bit-printed magnetization is almost straight for any pattern, while that of edge-printed magnetization has several ridges. On the other hand, the edge printing is robust for the change in the printing field, compared with the bit printing.
