The gap size of the write head in magnetic recording system is so small compared with full size head, which causes the difficulties in numerical analysis and design. In this paper, a two step of the analysis is presented. After the analysis of the full size head by using conventional three-dimensional finite-element method (FEM), the field gradient of the small gap region is computed by Laplacian analysis. Write field and field gradient of the longitudinal and perpendicular head are to be computed effectively. By using this algorithm, optimum shapes of the write head for high-density recording system could be designed.
