Abstract:
1. A magnetic head for recording and reproducing on a magnetic recording medium having a soft magnetic under layer, the magnetic head comprising a recording head including a main-pole and a return-pole, and a read head including a pair of reader shields and a magneto-resistive element sandwiched between said pair of reader shields, wherein the magnetic head further comprises a soft magnetic shield disposed so as to surround an upper part of a magnetic member constituting the magnetic head in a height direction of the element, and a side of the member in a track width direction, and wherein a distance between the soft magnetic shield and the magnetic member is longer than a distance between the soft magnetic shield and an air-bearing-surface, and wherein said soft magnetic shield is formed in the same plane, in the same thickness, and of the same material as at least one of layers of the magnetic member constituting the magnetic head.
