提出了一种新的，完全解析解的磁场中存在的软磁衬层的任意尺寸的薄膜磁头。假设每个磁极上的磁势为已知常数。傅立叶系数和场分量给出了两个特殊的情况下的实际利益。本文证明了近似的准确性，不需要傅立叶系数，但必须进行数值计算。
Presents a new, entirely analytic solution for the magnetic field of a thin-film head of arbitrary dimensions in the presence of a soft magnetic underlayer. The magnetic potential on each pole is assumed to be a known constant. Fourier coefficients and field components are given for two particular cases of practical interest. The paper demonstrates the accuracy of approximations that require no Fourier coefficients, but that must be evaluated numerically.
