Abstract
A magnetic head comprises a pole layer, a gap layer, a shield layer, a nonmagnetic layer, and a coil. The shield layer incorporates: a first layer disposed on the gap layer; a second layer disposed on the first layer; a two-layered coupling layer disposed on a region of the pole layer where an opening of the gap layer is formed; and a third layer disposed to couple the second layer to the coupling layer. The first layer defines throat height TH. The nonmagnetic layer is disposed on a side of the first layer. The coil is disposed on the nonmagnetic layer on a side of the second layer.
