Abstract

PURPOSE:To increase the bonding strength and the reliability and to make easy the bonding control, by bonding with the second film lower in melting and softening point than the non-magnetic film formed on the two core butt surfaces. CONSTITUTION:The I core 12 and C core 11 are formed from the substrate forming the SiO2 film 20 on the ferrite substrate 10, the front part of the I and C cores is masked, and the low melting point glass film 22 is formed only on the rear part 17 with sputtering by using the lead system glass of lower melting point than the SiO2 film. After that, the sputtering surface of the I core 12 and C core 11 is butted and bonded. Thus, since the bonding is made at the entire opposed surfaces of the head, the bonding strength can remarkably be increased and also the reliability in time aging of the head can be improved.
