A recording head has: a bottom pole layer and a top pole layer that include pole portions; a recording gap layer placed between the pole portions; and a thin-film coil located between the top and bottom pole layers, the coil being insulated from the pole layers. The top pole layer has a pole portion layer and a yoke portion layer. The step of making the yoke portion layer includes the steps of forming a frame made of an insulating material around a region where the yoke portion layer is to be formed; forming a layer including a magnetic material inside and on top of the frame; and forming the yoke portion layer with the layer remaining in the frame by flattening the top surface of the layer including the magnetic material so that the frame is exposed.
