引言我们已经表明，数值模拟可以解释的基本特征是两个的椭圆形的磁记录和的椭圆形的一个[1]。在该模拟中，将卷曲的磁化反转模式用于介质部件[2]，并且针对每个记录场水平冻结头的磁场分布。垂直记录时，由于Co-Cr层中的磁化强度分布改变了单极头与双层介质之间的磁相互作用，从而改变了磁头的额定头场。因此，我们开发了采用卷曲模式的有限元法（FEM）。我们可以同时分析磁相互作用和矢量记录机制。
Introduction We have already shown that the numerical simulation can explain basic charac ter is t i cs bo th o f the perpendicu lar magnet ic record ing and t h e longitudlnal one [l]. In that simulation, the magnetization reversal mode of curl ing is used t o medium part icles [2] and a magnetic f ie ld distr ibution of a head was frozen for each recording-field level. However the -rating headfield varies in the perpendicular recording, because the magnetic interaction between a single-pole head and a double-layer medium is changed by the magnetization distr ibution in a CO-Cr layer. Therefore, we developed the finite element method (FEM) adopting the curling mode. We could analyze the magnetic interaction and a vectorial recording mechanism at the same time.
