Method of manufacturing magnetic head for perpendicular magnetic recording |
摘要 |
A pole layer has an end located in a medium facing surface, the end having: a first side close to a substrate; a second side located opposite to the first side; a third side connecting an end of the first side to an end of the second side; and a fourth side connecting the other end of the first side to the other end of the second side. The second side defines a track width. The end of the pole layer located in the medium facing surface has a width that decreases toward the first side. The pole layer is disposed in a groove of a pole-layer-encasing layer made of a nonmagnetic insulating material, with a nonmagnetic conductive film provided between the encasing layer and the pole layer. The pole layer incorporates: a first layer located closer to the surface of the groove; and a second layer located farther from the surface of the groove.
