METHOD FOR FABRICATING MAGNETIC READ-WRITE HEAD ARRAY AND PRODUCT

A method for fabricating an array of read-write heads for a magnetic storage means, such as a disk or drum, is disclosed. Each head is comprised of a flux carrying means, such as a gapped magnetic loop inductively coupled to a flux producing means, such as a pair of coils. The coils, together with a portion of the associated addressing circuitry, are formed on a high resistivity substrate. The halves of the magnetic loops that lie on opposite sides of the coil assembly are fabricated in the relative position on two separate assemblies. The two assemblies are then bonded to opposite sides of the coil assembly so that the halves of the magnetic loops mate through holes in the substrate to form the complete gapped magnetic loops. The excess material of the assemblies is then cut away as required to leave magnetically isolated magnetic loops and the associated coils embedded within a solid body.
