Abstract: A magnetic head which comprises a pair of head chips 25, 26 each composed of a pair of plate-like magnetic cores 2,20, (21, 22) superposed on and joined to each other with a spacer 15 interposed therebetween and having a gap G1 (G2) at the junction, a pair of base plates joined to the pair of head chips 25, 26 individually and positioned on opposite sides of and in parallel to a plane containing the gaps G1, G2, each of the magnetic core having at one end thereof a head 31 with a small width substantially equal to the width of tracks and an end portion of increased width opposite to the head, a shield member 12 interposed between the head chips 25, 26 at the head portions, a stud portion 3 provided on at least one of the pair of magnetic cores and projecting toward the other core, and a coil 4 provided around the stud portion 3. A process is also disclosed for producing such magnetic heads wherein the pair of magnetic cores are positioned close to each other, and the gaps G1 and G2 are accurately positioned on the same plane.

Abstract: A read/write head for use with high coercivity and low coercivity magnetic stripe in multiple-track applications comprising a plurality of inductively wound read/write gaped cores (80, 82) and a shield (76) situated between the cores (80, 82) such that a non-magnetic space (86, 87) is formed between the shield (76) and each adjacent core (80, 82), the width of the shield (76) being no greater than the width of the non-magnetic spaces (86, 87).
