Abstract
A thin film magnetic head for perpendicular recording of a single-pole type has a flux enhanced part and a flux enhanced end of a main pole arranged on a leading side of the main pole in parallel with the cross track direction. The side surface of the main pole intersecting the cross track direction of the main pole is arranged on the track center side perpendicular to the track width. The field gradient of a perpendicular magnetic field on the trailing side of the main pole and near both ends of the track is made steep to realize a higher areal recording density as a result.
