摘要：
A magnetic head incorporates: a medium facing surface; a coil; a pole layer; first and second shields disposed to sandwich the pole layer therebetween; a first gap layer disposed between the first shield and the pole layer; a second gap layer disposed between the second shield and the pole layer; and a substrate. The first shield is located closer to the substrate than the second shield. The first shield has a first layer and a second layer disposed between the first layer and the first gap layer.
