信息位之间的最小磁化转变宽度决定了可实现的记录线密度。该宽度的最终极限由连续介质颗粒结构决定。过渡宽度限制对晶粒尺寸平均值和标准偏差的依赖性是在没有磁化过渡形状的先验假设的情况下给出的。讨论了一种结合有限晶粒尺寸和过渡宽度磁场梯度的简化方法。
The minimum magnetization transition width between information bits determines achievable recording linear density. The ultimate limit of this width is determined by the continuous media granular structure. The dependence of the transition width limit on grain size mean and standard deviation are given without an a priori assumption of magnetization transition shape. A simplified approach to combine finite grain size and magnetic field gradient for transition width is discussed.
