利用信号处理准则分析了环形（卡尔奎斯特）磁头和垂直磁各向异性记录介质的回读信号。利用Beardsley和Potter提出的自洽模型研究了探测高密度跃迁的可行性。模拟回读信号的时域和频域特性进行了讨论。提出了一个简化的线性系统模型，其中包括媒体方向的影响。讨论了“垂直”信道的滤波和检测方法。
The readback signals from a ring (Karlqvist) head and recording medium with perpendicular magnetic anisotropy are analyzed using signal processing criteria. The self-consistent model developed by Beardsley and Potter is used to study the feasibility of detecting transitions at high densities. Simulated readback signals are discussed in terms of time and frequency domain characteristics. A simplified linear system model is proposed which includes the effects of media orientation. Filtering and detection methods for the "vertical" channel are discussed.
