Abstract

PURPOSE: To obtain a magnetic head of narrow track width large in inductance and output by self-welding magnetic materials, forming a couple of core blocks, at rear- part gap-part junction part.
CONSTITUTION: A couple of core blocks are formed of magnetic materials of high magnetic permeability such as permalloy. Next, the both are butted together with a prescribed nonmagnetic gap interposed and after the front-part gap part is bonded with a nonmagnetic metal, the rear-part gap part is connected in one body by welding at a high temperature. This block is sliced into individual head chips. Each chip is polished to obtain a narrow-track magnetic head of ≤10μ track width and about 1μ gap length. This head has high junction-part bonding strength and excellent characteristics.
