Abstract

PURPOSE: To obtain a stereophonic multichannel magnetic head with improved crosstalk characteistics by bonding dummy parts after performing back work of a material and then by inserting a front channel plate through a spacer after channel work.
CONSTITUTION: A ferrite material, etc., is worked to form gap 12 and front cores 13 and 14. Further, dummy parts 17 and 18 are connected after back work. Next, channel work is carried out to provide front groove part 19 and at the same time, track step parts 22 and 23 are formed so that track parts 20 and 21 will be formed. Into front groove part 19, front channel shield plate 27 made of permalloy, etc., is inserted and fixed via spacers 24 and 25. Next, back work is carried out again to provide leg parts 28 of front cores. In this method, a multichannel magnetic head for VTR and stereophonic with track width reduced can be obtained.
