Perpendicular magnetic recording head with longitudinal magnetic field generator to facilitate magnetization switching |
摘要 |
A perpendicular magnetic recording head includes a perpendicular writing pole and a longitudinal field generator which rotates the magnetization of the perpendicular recording media prior to writing, thereby facilitating magnetization switching. The longitudinal magnetic field may be provided by a narrowed gap between the trailing write pole and the leading return pole of the head. The gap structure is designed to provide a fringing magnetic field between the poles which generates the longitudinal magnetic field in perpendicular recording media as the media travels under the perpendicular writing pole.
