单层膜垂直磁记录单极型磁头读出的频率特性

The Readback Frequency Characteristic of the Single-Layer Medium in Perpendicular Recording with a Single-pole-Head

从理论上对单层膜等距全“１”垂直磁化单极型磁头的读出过程进行了理论分析。给出了单层膜垂直磁记录单极头读出过程的频谱曲线。由此可看出单层膜单极头垂直磁记录系统所能达到的极限记录位密度。

An anlysis is made on the readback process of the single layer medium with a single-pole-head during perpendicular magnetization of all“1”with equal distance.The roll-offcurve is given,from which the limit recording be density of the perpendicular magneticrecording by a single-pole-head can be easily found.
