本文提出了一个新的跃迁参数和非线性跃迁位移的解析记录模型。在该模型中，采用Schwartz-Christoffel变换计算介质中的退磁场，并结合单极写入器和软衬层的影响。侧转的Westmijze场用于计算头场。磁头磁场和退磁场都在记录介质的厚度上平均。利用Williams-Comstock方法确定了过渡参数。轨道边缘效应不包括在内。从我们的模型计算的孤立脉冲（T50）的密度和过渡宽度的S/N依赖性与公布的数据吻合得很好。当考虑写入极图像时，计算的NLTS减小（e. G.从15%到10%），但是过渡参数没有显著变化。
A new analytic perpendicular-recording model for the transition parameter and nonlinear transition shift (NLTS) has been developed. In this model, the Schwartz-Christoffel transformation is used to calculate the demagnetizing field in the medium, combining the effects of the single-pole writer and the soft underlayer. The Westmijze field turned sideways is used to calculate the head field. Both the head field and the demagnetizing field are averaged over the thickness of the recording medium. The Williams-Comstock approach is utilized to determine the transition parameter. Track-edge effects are not included. S/N dependence on the density and the transition width of the isolated pulse (T50) that are calculated from our model agree well with published data. When the write pole image is considered, the calculated NLTS decreases (e. g. from 15% to 10%), but the transition parameter does not change significantly.
