Patent ID: 7286321

Claim:
A thin-film magnetic head comprising: a lower core layer formed so as to extend in a height direction from a surface opposing a recording medium; a magnetic layer connected to the lower core layer directly or indirectly at a position spaced from an opposing surface in the height direction by a predetermined distance; and a coil layer toroidally winding around the magnetic layer; and a raised layer provided on the lower core layer at a position spaced in a track width direction from a center of the lower core layer in a track width direction, wherein the toroidal coil layer is connected to a plurality of first coil pieces formed between the lower core layer and the magnetic layer and a plurality of second coil pieces formed on the magnetic layer, wherein upper surfaces of the first coil pieces are covered with an insulating layer other than connection surfaces to the second coil pieces, the connection surfaces of the first coil pieces being raised upward and exposed from an upper surface of the insulating layer so that the second coil pieces are formed in contact with the connection surfaces of the first coil pieces, wherein part of the first coil pieces is mounted on the raised layer, part of the upper surfaces of the first coil pieces mounted on the raised layer are exposed from the upper surface of the insulating layer, so that the exposed surface becomes the connection surface, and wherein the upper surface of the lower core layer is formed as a flat surface over a region opposing the first coil pieces between a pair of the raised layers and formed below both sides of the first coil pieces.
