Abstract :
In this paper, we study the effect of the write head field on the signal-to-noise ratio and bit error rate of a magnetic recording channel, and optimize the write head for perpendicular magnetic recording (PMR). Six parameters of the write head for PMR are studied in the design. An optimal solution of the write head is obtained using the design of experiment methodology, the optimum writer field is verified, and the improved recording performances are achieved with the optimally designed write head.
