Magnetic head and magnetic recording and reproducing device

Abstract

According to one embodiment, a magnetic head includes a magnetic pole, a first shield, a magnetic layer, first and second conductive layers. The magnetic layer is provided between the magnetic pole and the first shield. The first conductive layer contacts the first shield and the magnetic layer, is provided between the first shield and the magnetic layer, and includes at least one selected from Cu, Ag, and Au. The second conductive layer is provided between the magnetic pole and the magnetic layer. The second conductive layer includes first and second regions. The first region contacts the magnetic layer and includes at least one first element selected from Cu, Ag, Au, Al, Ti, Ru, Mg, and V. The second region is provided between the first region and the magnetic pole and includes at least one second element selected from Ta, Pt, W, Mo, Ir, Cr, Tb, Rh, and Pd.
