发明名称 Composite magnetic head having accurately aligned gaps
摘要 A magnetic head which comprises a pair of head chips each composed of a pair of plate-like magnetic cores superposed on and joined to each other with a spacer interposed therebetween and having a gap at the junction, a pair of base plates joined to the pair of head chips individually and positioned on opposite sides of and in parallel to a plane containing the gaps, each of the magnetic core having at one end thereof a head 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 interposed between the head chips at the head portions, a stud portion provided on at least one of the pair of magnetic cores and projecting toward the other core, and a coil provided around the stud portion. 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 are accurately positioned on the same plane.
