摘　　要：一般地,录像机磁头的磁导率仅用一个圆环状磁头材料的磁导率测定值近似代替,这一圆环并不是真正的磁头。在本文中,我们通过一个简单的缝隙因子模型和一些磁头的实际测定数据,通过一个线性回归的方法,使得录像机磁头中有效磁导率的实验测定成为可能。In general,the magnetic permeability of the VTR magnetic head is replaced by a measured data of the magnetic permeability,the data is measured through a circle ring of the magnetic head material only. The circle ring is not a actual magnetic head.In this paper, we used a simple gap factor model and some measured data of actual magnetic heads, made it become possible about the experimental measurement of the effect magnetic permeability in the VTR magnetic head,by a linear regression method.
