Perpendicular magnetic recording head
摘要:
In a perpendicular magnetic recording head comprising a main magnetic pole layer and a return yoke layer which have respective front end faces exposed at a surface opposing a recording medium and are laminated with a nonmagnetic material layer interposed therebetween on the medium-opposing surface, an end magnetization control layer for generating an exchange-coupling field is provided on the upper or lower side of both end parts in a track width direction of the return yoke layer. The exchange-coupling field fixes magnetization in the end parts to the track width direction.
