A magnetic head comprising:
- a magneto-resistive head;
- a bottom pole spaced a predetermined distance from the magneto-resistive head;
- a top pole spaced a predetermined distance apart from the bottom pole on a side opposite to the magneto-resistive head;
- an inductive write coil for forming a magnetic field at the bottom and top poles;
- and
- a magnetic shield layer positioned over the top pole on a side of the top pole opposite to the side adjacent to the bottom pole, wherein the width of the magnetic shield layer is wider in width than a width of the top pole.
