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.
