A single-pole perpendicular magnetic recording head contains a bevel angle promotion layer that facilitates the fabrication of the bevel angle in a trapezoidal main pole. The bevel angle promotion layer is made of a non-magnetic material that is softer than the material (e.g., Al.sub.2O.sub.3) that normally underlies the main pole. In one embodiment, the bevel angle promotion layer is formed between an end of the yoke and the air bearing surface (ABS), with the top surface of the bevel angle promotion layer being substantially coplanar with the top surface of the yoke. In other embodiment the bevel angle promotion layer is integrated with a leading edge taper material, which is formed of a magnetic material, to broaden the magnetic flux path between the yoke and the main pole.
