A recording head has a bottom pole layer, a top pole layer, a recording gap layer, and a thin-film coil. The bottom pole layer includes a first portion and a second portion. The first portion is located in a region facing toward the thin-film coil. The second portion is connected to the first portion and defines a throat height. The thin-film coil is located on a side of the second portion. The top pole layer includes a track-width-defining portion. An end of the track-width-defining portion opposite to the air bearing surface is located closer to the air bearing surface than an end of the second portion opposite to the air bearing surface. A portion of the second portion has a width the same as that of the track-width-defining portion.
