单层膜垂直磁记录环形头读出时头盘结构参数选择方法的理论研究

Theoretical Study on the Selection of Head-Medium Parameters for Readout Process of Isolated Perpendicular Magnetization for Single-Layer-Medium with Ring-Type Head

本文用镜像法推导了单层膜孤立垂直磁化有限前隙深度环形头读出波形电压表达式。并基于此表达式从理论上分析了头盘结构参数的选择方法。

Readout voltage of isolated perpendicular magnetization for single-layer-medium with ring-type head with finite length is calculated by imaging methodhere. The selection method of head-medium structure parameters is studied based on theformula.
