Abstract:
According to one embodiment, a magnetic head includes a magnetic pole, first and second shield regions, and a first stacked body. A direction from the magnetic pole toward the first shield region is aligned with a first direction. A direction from the magnetic pole toward the second shield region crosses the first direction. The first stacked body is provided between the magnetic pole and the second shield region. The first stacked body includes a first magnetic layer including at least one selected from the group consisting of Fe, Co, and Ni, a first conductive layer provided between the magnetic pole and the first magnetic layer, and a second conductive layer provided between the first magnetic layer and the second shield region. The first direction is aligned with a direction of relative movement between the magnetic pole and a magnetic recording medium. The magnetic pole opposes the magnetic recording medium.
