Abstract
According to one embodiment, a magnetic head includes a reproducing section. The reproducing section includes a first shield, a second shield, a third shield, a fourth shield, a first magnetic layer, a first intermediate layer, and a second intermediate layer. A second direction from the third shield to the fourth shield crosses a first direction from the first shield to the second shield. The first magnetic layer is provided between the first shield and the second shield and between the third shield and the fourth shield. The first intermediate layer is provided between the first shield and the first magnetic layer, and is nonmagnetic. The second intermediate layer is provided between the first magnetic layer and the second shield, and is nonmagnetic. The second intermediate layer length of the second intermediate layer is shorter than a first intermediate layer length of the first intermediate layer along the second direction.
