| 摘 要： | 本文对高道密度垂直磁记录单极头的读出过程进行了理论分析，考虚到垂直磁记录方式的记录位长远小于单极型磁头厚度，在不计及漏磁的情况下，用镜像法简化地推导了双层膜窄道宽垂直磁记录单极头读出波形电压表达式，由此可以看出影响垂直磁记录单极头磁记录系统实现高道密度的因素。

| Abstract: | Theoretical analysis of readback process of high track density perpendicular recording with single-pole-head are presented here. As the recording bit length for the perpendicular magnetic recording pattern is shorter than the head thickness, an expression.for the readback voltage of an isolated perpendicular magnetization for the double-layer-medium is derived by the mirror image method with the leakage flux neglected. The effects of some factors on the realization of high track density can be easily seen from the expression. |
