摘要： An encasing section that accommodates a pole layer includes an encasing layer having an encasing groove, and a nonmagnetic film disposed in the encasing groove at a position between the encasing layer and the pole layer. The pole layer includes a track width defining portion and a wide portion. The distance from a medium facing surface to the boundary between the track width defining portion and the wide portion is within a range of 10 to 300 nm. The track width defining portion has a first side surface and a second side surface, while the wide portion has a third side surface contiguous to the first side surface, and a fourth side surface contiguous to the second side surface. The encasing layer has a first wall surface and a second wall surface that form the encasing groove. The distance between the third side surface and the first wall surface is smaller than the distance between the first side surface and the first wall surface, and the distance between the fourth side surface and the second wall surface is smaller than the distance between the second side surface and the second wall surface.

摘要： A magnetic layer for writing incorporates: a pole layer having an end face located in a medium facing surface; and an upper yoke layer. A first magnetic layer for flux concentration is connected to the pole layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a first coil to pass. A second magnetic layer for flux concentration is connected to the upper yoke layer at a location away from the medium facing surface, and allows a magnetic flux corresponding to a magnetic field generated by a second coil to pass. When seen in the direction orthogonal to the interface between the second magnetic layer and the upper yoke layer, this interface is disposed at a location that does not coincide with the interface between the first magnetic layer and the pole layer.

摘要： A thin-film magnetic head comprises a bottom pole layer having a surface that faces toward a write gap layer. This surface incorporates a first surface including an end portion located in the air bearing surface, and a second surface located away from the air bearing surface. There is a difference in level between the first surface and the second surface, so that the second surface is located farther from the top pole layer than the first surface. A top pole layer incorporates a throat height defining layer, an intermediate layer, and a yoke portion layer. The yoke portion layer includes a track width defining portion for defining the track width. Each of the throat height defining layer, the intermediate layer, and the track width defining portion has a width equal to the track width.
