Abstract
We made single crystal ferrite heads with various thermal stress by changing the annealing temperature, and we traced the source of the poor performance by experiments. As a result, we revealed that the deterioration of the ferrite permeability near the gap determines, in large part, the operating characteristics of the ferrite head. Considering the result, we developed a calculation method that enables us to estimate the relationship between head characteristics and magnetoelastic effect in ferrite heads
