Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic reproducing head and a manufacturing method thereof capable of reducing the occurrence of a side read to the utmost even when the track width is narrowed.  <P>SOLUTION: A (first) nickel iron layer 13, a (second) antiferromagnetic layer 14, a nonmagnetic layer 31, a (second) nickel iron layer 32, and a read layer 15 are sequentially laminated on both sides of a spin valve structure 10 while keeping in contact with a side slope 10S. The nickel iron layer 13 applies a permanent longitudinal bias magnetic field in a first direction to the spin valve structure 10 in cooperation with the antiferromagnetic layer 14. The nickel iron layer 32 is magnetized in a second direction in anti-parallel with the first direction. The nonmagnetic layer 31 eliminates exchange coupling between the nickel iron layer 32 and the antiferromagnetic layer 14. The nickel iron layer 32 absorbs magnetic flux from a recording medium track (adjacent track) at a position opposed to the real layer 15 to block the penetration of the magnetic flux into the spin valve structure 10. Thus, the side read can be avoided.  <P>COPYRIGHT: (C)2004,JPO
