Summary:A magnetic write head for perpendicular magnetic recording that is resistant to write pole and trailing shield protrusion. The write pole includes a magnetic return pole that is magnetically connected with the trailing shield, the return pole being resistant to deformation or recession such as from mechanically abrasive slider cleaning operations such as soda blast.
