Patent attributes
The thin-film magnetic head comprises a lower magnetic pole layer, an upper magnetic pole layer and a first thin-film coil. A resist film made of an organic insulating material is interposed between turns adjacent to each other in the lead constituting the first thin-film coil. The first thin-film coil has a minimum width part and a maximum width part. The minimum width part is arranged closer to an air bearing surface than is a second upper magnetic pole part, while the whole upper face of the minimum width part is covered with the resist film. The maximum width part is arranged on the side farther from the air bearing surface than is the second upper magnetic pole part, while the upper face of the maximum width part is formed with a resist-uncoated area free of the resist film.
