垂直介质的读回信号可以表示为介质磁荷乘以间隔损耗因子和磁头特性矩阵。给出了具有软衬层的垂直记录介质的间隔损耗因子的简单解析表达式。垂直介质的间隔损耗对飞行高度和记录波数的依赖关系与纵向介质的间隔损耗对飞行高度和记录波数的依赖关系显着不同。间距损耗因子可以解释为当介质电荷片位置移动时为了保持头部处的场恒定而施加在介质电荷片上的因子。
The read back signal from a perpendicular medium can be expressed as the medium magnetic charge multiplied by the spacing loss factor and the head characteristic matrix. The spacing loss factor for a perpendicular recording medium with a soft underlayer is given a simple analytical expression. The dependence of the spacing loss on the flying height and the recording wave number for a perpendicular medium is significantly different from that for a longitudinal medium. The spacing loss factor can be interpreted as the factor to be applied on the medium charge sheet in order to keep the field at the head constant when the sheet position is shifted.
