使用三维涡流瞬态有限元分析研究了具有双层介质的窄磁道单极（SPT）写入头的记录场。在计算中，假设软磁底层的厚度为100 nm。结果表明，磁道宽度为 100 nm 时磁头场强度较大，后缘处记录场梯度较大。
The recording field of a narrow-track, single-pole (SPT) write head with a double-layered medium was investigated using three-dimensional eddy current transient finite element analysis. In the calculations, a soft-magnetic underlayer with a thickness of 100 nm was assumed. The results illustrate a large head field strength at a track width of 100 nm and a large recording field gradient at the trailing edge.
