    摘要: A magnetic head comprises a pole layer, a shield layer, a gap layer disposed between the pole layer and the shield layer, and a coil. The shield layer incorporates a first layer, a second layer, a third layer and a fourth layer that are disposed on the gap layer one by one. The first layer has an end face located in a medium facing surface. The second layer has: a first surface located in the medium facing surface; a second surface touching the first layer; and a third surface opposite to the second surface. The third layer touches the third surface of the second layer. An end face of each of the third and fourth layers closer to the medium facing surface is located at a distance from the medium facing surface.
