Title: Magneto-resistive element
Inventor: YANAGI SHUJI
IPC: G11B5/39
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To enable to increase a reproducing output by increasing a specific resistance of a soft-magnetic layer to increase a branching ratio of sense current to a magneto-resistive layer. SOLUTION: A soft-magnetic layer 23 is formed of a high permeability ferrite having the composition of Fe-O or M-Fe-O (where, the element M is at least one or more of Mn, Co, Ni, Ba, Sr, Y, Gd, Cu and Zn).
