Abstract:
A magnetoresistance element comprising:(a) a MR layer having a width corresponding to a recording track width of an applicable magnetic recording medium; (b) a pair of vertical biasing layers disposed at each side of said MR layer to be overlapped with each end of said MR layer; inner opposing ends of said pair of vertical biasing layers being contacted with said MR layer; (c) a pair of dielectric layers formed on said pair of biasing layers; inner opposing ends of said dielectric layers being contacted with said MR layer; and (d) a pair of electrode layers formed on said pair of dielectric layers; inner opposing ends of said pair of electrode layers being contacted with said MR layer, thereby electrically connecting said pair of electrode layers to said MR layer; a distance between said inner opposing ends of said pair of electrode layers being smaller than a width of said MR layer, wherein each of said inner opposing ends of said pair of dielectric layers is located between one of said innermost ends of said pair of electrode layers and a corresponding one of said innermost ends of said pair of vertical biasing layers.
