A thin-film magnetic head comprises: a first magnetic layer and a second magnetic
layer each of which includes a magnetic pole portion, the first and second magnetic
layers being magnetically coupled to each other at a distance from the medium facing
surface ABS; a gap layer provided between the first and second magnetic layers;
and a thin-film coil at least a part of which is disposed between the first and
second magnetic layers. The second magnetic layer has a pole portion layer and
a yoke portion layer. The pole portion layer has a saturated magnetic flux density
equal to or greater than that of the yoke portion layer. The yoke portion layer
includes: a first layer and a second layer, of which the first layer is in contact
with the first magnetic layer and a surface of the pole portion layer that is closer
to the gap layer; and the second layer is in contact with the first layer, the
rear end surface of the pole portion layer and both side surfaces of the pole portion
layer in the width direction.
