PROBLEM TO BE SOLVED: To provide a magnetic head structure that can maintain required sensitivity, even for narrow tracks and make it compatible with suppression of the Barkhausen noise. SOLUTION: This magnetoresistive effect head has magnetoresistive effect films (11 to 15), hard magnetic films 22a, 22b provided at their both ends to stabilize the magnetoresistance effect, and neighboring electrodes 23a, 23b to supply current for sensing. Electrodes 21a, 21b are provided at the boundary of the magnetoresistive effect films and the hard magnetic films. These electrode are made by a self-alignment process which uses the same mask as used, when making the magnetoresistance effect films. The hard magnetic films and magnetoresistance effect films (11 to 15) have no region in which they come into direct contact with. COPYRIGHT: (C)2004,JPO
