Stripe amorphous film which has closure domain stracture has been investigated to clarify effect of induced magnetic anisotropy on stabilization of domain wall. The aging temperature is fixed at 150°C in order to expose speciments to the same temperature of fabrication process as magnetic head. The decrease of initial permeability and change of B-H curves after aging are observed. These phenomena can be interpreted in terms of the stabilization of the domain wall by locally induced magnetic anisotropy. The elevation of pre-annealing terperature higher than 350°C is effective to maintain soft magnetic properties of stripe and thin film head.
