磁记录中的退磁效应必须不是作为静态自退磁来评估，而是作为磁头磁场施加到介质时瞬间的动态退磁场来评估。从这个事实来看，有必要在介质中获得自洽的磁化分布。描述了计算方法及其结果。阐明了纵向磁化强度和矢量磁化强度之间的关系。正弦记录中的记录退磁以及数字记录中的脉冲宽度和峰移的实验结果被解释为与记录过程中退磁场的动态行为有关的新现象。
The demagnetization effect in magnetic recording must be evaluated, not as static self-demagnetization, but as a dynamic demagnetizing field at an instant when the head field is applied to the medium. From this fact it becomes necessary to obtain a self-consistent magnetization distribution in the medium. A method of calculation and its results are described. The relation between the longitudinal and the vector magnetization is clarified. The experimental results of the recording demagnetization in sinusoidal recording and the pulse width and the peak shift in digital recording are interpreted as the new phenomena that is related to the dynamical behavior of the demagnetizing field in the recording process.
