Abstract

Method of manufacturing a multitrack magnetic head comprising magnetic circuits relatively separated by shield plates and each of which has two pole pieces, magnetic circuits that are housed in a box of two elements, provided with depressions for the pole pieces and shield plates in which the polar parts are polished during manufacture, after which the resulting halves of the head are joined with the interposition of the shield plates and the air gap plates by means of molding resin characterized by the use of box halves in which the depressions of each of the two adjacent pole pieces, which must be separated by a shield plate, open into the depression for the shield plate at an acute angle, an auxiliary plate of at least the same thickness that the shield plate is placed first in the depression for the shield plate, after which the pieces Ovals are placed in their depressions to the left and right of the auxiliary plate, pushed against the plate and fixed in this position by means of the adhesive, after which in each half of the head the terminal surfaces of the pole pieces are ground and the auxiliary plate, before or after the grinding, is removed and then each of the two halves of the head if the coils have not yet been provided on the pole pieces, after the placement of the same, are joined with the interposition of the shielding plates and introduction of the interlock plates, by means of molding resin and finally, the magnetic head is finished.
