Abstract
PURPOSE: To offer a magnetic head excellent in the gap in-line property and time aging stability, by respectively coupling two front cores one end of which is magnetically open, to a nonmagnetic substance incorporated at the open ends.
CONSTITUTION: After bonding a magnetic substance block 13 of sendust material to a nonmagnetic substance block 14 with silver solder foil, a groove 15 is provided for wrap processing between a front gap surface 16 and a back bonding surface 17. Next, sputter vapor deposition of SiO2 is made on a surface 16, and it is butted to one block at a surface 17 via a silver solder foil 19 and gap formation is made by heat treatment. Next, a channel separation groove 20 is processed to obtain a member 23 in which the front core is coupled to the nonmagnetic substance 14. A 2- channel magnetic head 28 is obtained by bonding a back core 27 to it. Thus, since the same metal material and solder material as the core member are coupled as adhesives, excellent gap in-line property and time aging stability can be given.
