A sloped write pole design is assessed for perpendicular magnetic recording at high areal densities. Modeling shows that there is a significant increase in magnetic field from the sloped pole design over the conventional pole design at a fixed write width. Spin stand measurements were carried out in order to investigate the recording benefits of the sloped pole design. Writing improvements from this writer were best observed at high media coercivity. © 2008 American Institute of Physics;
