摘要： A pole layer has a track width defining portion and a wide portion. The pole layer has: first and second side surfaces located opposite to each other in a first region extending from a medium facing surface to a position at a distance of 10 to 300 nm from the medium facing surface; third and fourth side surfaces located in a second region other than the first region; a fifth side surface located at the boundary between the first and second regions and connecting the first and third side surfaces to each other; and a sixth side surface located at the boundary between the first and second regions and connecting the second and fourth side surfaces to each other. The distance between the first and second side surfaces taken in the track width direction decreases with decreasing distance from the top surface of the substrate. The angle formed by the third and fourth side surfaces with respect to the direction orthogonal to the top surface of the substrate is smaller than that formed by the first and second side surfaces with respect to the direction orthogonal to the top surface of the substrate.

摘要： A shield incorporates: a first layer, a second layer, a third layer, a first coupling portion, and a second coupling portion. The first layer has: a first surface located in a region of a medium facing surface forward of an end face of a pole layer along the direction of travel of a recording medium; a second surface opposed to the pole layer; and a third surface opposite to the second surface. The second layer touches the third surface. The third layer is disposed in a region sandwiching the pole layer with the first layer. The first coupling portion couples the first layer to the third layer without touching the pole layer. The second coupling portion is located farther from the medium facing surface than the first coupling portion and couples the pole layer to the third layer.
