摘要:
A method of manufacturing a ferrite magnetic transducer head is disclosed, in which two Mn - Zn ferrite core blocks are bonded together with glass material containing Fe.sub.2 O.sub.3 and ZnO. By proper thermal treatment, homogeneous dispersion of fine precipitates of Zn - Fe - O is formed in the bonding glass.
