Slotted sensor in yoke-type magneto-resistive head

摘要

A multitrack magneto-resistive head is comprised of an array of thin- film yoke-type core structures. In the back gap of each such core structure, there is a sense-current-carrying magneto-resistive flux responsive element. To prevent excessive sense current flow, and insensitivity as caused thereby, the invention teaches that slotting of the magneto-resistive element in the region thereof where such element connects into such back gap will alleviate both such problems.
