Abstract

PURPOSE: To obtain a magnetic head of excellent joining strength by providing streak grooves on back-gap part junction surfaces of a couple of core half bodies and by charging the streak grooves with a soldering agent in the manufacture of a magnetic head formed of joined core half bodies.
CONSTITUTION: Core block 30 has front-gap constitution part 31, back gap constitution part 32, winding-hole groove 33, and grooves 34, 35, 36, and 37 for fusion welding and after the above-mentioned grooves are provided with copper-plating film 38, the grooves are filled with silver solder. Next, spacer 40 is provided on front-gap constitution part 31 of the above-mentioned core block 30 and then the junction surfaces of core blocks 30 and 30' are butted again each other; and the both are heated to fuse the soldering agent in the grooves, thereby joining both the blocks into one body. Next, the united core block is cut along a surface, crossing the contact surface at right angles, to a thickness of about 200μ and then thickness- worked to a fixed track width, thereby obtaining a main core.
