Shield with uniform magnetic properties for a perpendicular magnetic recording head

A magnetic head, comprising:

• a write pole;
• an amorphous metal layer comprising an electrically conductive material, wherein the amorphous metal layer is in direct contact with the write pole, wherein the amorphous metal layer surrounds the write pole on three sides of the write pole when viewed from an air bearing surface of the magnetic head;
• and
• a magnetic trailing shield, wherein the amorphous metal layer is between the trailing shield and the write pole.

A magnetic head comprising:

• a write pole, wherein the write pole comprises a first side and a second side opposite the first side when viewed from an air bearing surface of the magnetic head, wherein the first side is longer than the second side;
• an amorphous metal layer comprising an electrically conductive material, wherein the amorphous metal layer surrounds the write pole on three sides of the write pole when viewed from the air bearing surface of the magnetic head, wherein the three sides include the first side, and wherein the amorphous metal layer is in direct contact with the first side of the write pole;
• and
• a magnetic trailing shield, wherein the amorphous metal layer is between the trailing shield and the write pole.
