摘要：

An approximate 3-D micromagnetic model of a shielded, finite stripe height, dual element Magnetoresistive head is developed. It is shown that asymmetric bias profiles in the cross track direction arise from uniform bias magnetic fields. These asymmetric bias profiles appear in addition to the previously reported anisotropic signal flux propagation that occurs with respect to MR sensor width edges. In addition, DELTA-theta contours and track profile response curves that arise due to simulated recorded magnetization signal fields are presented.
