Magnetic head for perpendicular magnetic recording having a main pole and a shield
A magnetic head includes a magnetic structure incorporating a write shield. The magnetic structure is formed to include a first magnetic layer, a second magnetic layer stacked on the first magnetic layer, and a seed layer. The first magnetic layer has a front end face located in the medium facing surface and a top surface. The second magnetic layer has a front end face located in the medium facing surface and a bottom surface. The top surface of the first magnetic layer includes a first region including an end located in the medium facing surface and a second region farther from the medium facing surface than the first region. The seed layer is not present on the first region of the top surface of the first magnetic layer but is present on the second region.
