  • MAGNETIC HEAD AND METHOD OF MANUFACTURING THEREFOR
    Publication number: 20090190257
    Abstract: A magnetic head includes a magnetic pole for writing. The magnetic pole is formed by laminating a first magnetic layer and a second magnetic layer so as to sandwich a write gap on the magnetic pole end side. The second magnetic layer is formed to be laminated on the write gap in a region in which the write gap is provided. The second magnetic layer is laminated on an insulating layer via an adhesive layer in a region other than the write gap.
