MAGNETIC CONVERTING ELEMENT AND THIN FILM MAGNETIC HEAD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic converting element and a thin film magnetic head with resistance characteristics for facilitating a countermeasure to super- high density recording. SOLUTION: This MR element 110 of a magnetic converting element is provided with a laminate 20 including alternately laminated plural magnetic layers 22a-22g and plural non-magnetic layers 21a-21g, The laminate 20 is provided with a first area 20a and a second area 20b divided into the laminated direction. Materials or compositions constituting the magnetic layers are made different from each other in the first area 20a and the second area 20b of the laminate 20. Thus, it is possible to obtain a large resistance value and a large resistance change rate.
