Abstract

PURPOSE: To make a multi-element magnetic head high-sensitivity and low-crosstalk by shortening dimensions of a core half material, where no winding hole is provided, of a pair of core half materials and arranging them so that respective winding holes may be alternative and respective magnetic gaps may be arranged on the same line.
CONSTITUTION: Plural winding holes 13 are formed on main faces 21A and 22A of a pair of core half material blocks 21 and 22, and a glass bar and glass powder are put in glass bar insertion hole 24 and holes 13 after gap spacer 23 is caused to adhere to a prescribed region of main face 22A of one block 22 by evaporation, etc., and blocks 21 and 22 are so joined that winding holes 13 of one block may be placed between holes 13 of the other block respectively, and glass is fixed by melting, thereby forming magnetic gap g. Next, grooves 25 and 26 of width x larger than or equal to width w winding hole 13 are cut at a prescribed distance from magnetic gap g in respective blocks 21 and 22. Next, these half material blocks 21 and 22 are joined to nonmagnitic support material 10, and next, they are polished to prescribe track width t, thus separating plural cores 12. Next, winding 14 is provided.
