3-D FEM analysis of SPT head dimension on recording characteristics

Abstract

IntroductionThe cross-track interference in thc write process becomes a serious problem for high density magnetic recording. The discrete track media may be attractive to reduce the cross-track interference. The deviation of head from the centerline of track will affect the cross-track interference. In this paper, the effect of the width of write head on behavior of flux and magnetization in the case of continuous track media and discrete track media is investigated using 3-D readwrite simulation system [l]. The effect of width of read head on the output is also examined. SPT Head Model and Analysis Condition Fig.1 shows a 112 region of the SPT head model analyzed. Thc saturation flux density B, of
