摘要：
A soft magnetic layer is employed in place of the nonmagnetic insulating layer in a yoke type or flux guide type magnetoresistive head in which the magnetoresistive element is provided with a yoke or flux guide via a non-magnetic insulating layer which overlaps the magnetoresistive element, in part. Thus, leakage magnetic field can be guided effectively and playback output can be improved.
