ABSTRACT:
A perpendicular magnetic recording head is provided. The perpendicular magnetic recording head includes a main magnetic pole layer overlapped with a sub-yoke layer. The sub-yoke layer having a multiple-magnetic domain includes a magnetic domain having dominant track-widthwise component in contact with a front end face of the sub-yoke layer. A main magnetic pole layer24is overlapped with the magnetic domain35band is affected by the magnetic domain35b.
