摘要: A longitudinal bias layer and an electrode are formed on a non-magnetic material layer. The the partially removed by etching technique so that narrow gap defining track width Tw is in Furthermore, three-layer film consisting of, from bottom to top, magnetoresistance effect layer, transverse or otherwise spin valve of free magnetic fixed above structure. then remains only above-described shape side walls precisely determined resultant exhibits excellent detection characteristics. has good coupling with
