Thin film magnetic head for reducing side-fringing |
摘要 |
The leak magnetic field generated from the upper core layer toward the upper magnetic pole layer can concentrate in the vicinity of the gap layer to suppress side-fringing from generating while increasing the overwrite, by making the saturation magnetic flux density Bs1 of the upper magnetic pole layer to be higher than the saturation magnetic flux density Bs2 of the upper core layer, and by directly bonding the upper core layer on the upper magnetic pole layer.
