PROCESS FOR PRODUCING MAGNETIC HEADS

摘要

A method of making of magnetic head having core halves made from ferrite with a sputtered or vaporized soft magnetic alloy of a high permeability such as sendust on the ferrite. The operating magnetic gap of the head is sefined by the soft magnetic alloy of a high permeability. The metal includes providing a longitudinal groove in a ferrite block which serves as the base material and filling this groove with a non-magnetic material such as glass. Thereafter providing vertcial grooves along the block perpendicular to the longitudinal groove. The vertical grooves are vaporized or sputtered with the soft magnetic alloy of high permeability in such a manner that they are completely filled. The block is then halved along the center of the longitudinal groove, ground so as to smooth the adjecent surfaces and provide a coil winding groove and rejoined together via a bonding or adhesive layer. It is then ground to provide the proper head shape with the individual heads then separated from the block.
