Patent ID: 8264798

Claim:
A magnetic recording head comprising: a write pole tip having a pole face arranged parallel to an air bearing surface of the magnetic recording head, a leading surface having a leading edge at the pole face, a first side surface having a first side edge at the pole face, a second side surface having a second side edge at the pole face, and a trailing surface having a trailing edge at the pole face; a shield surrounding the first side surface, the trailing surface, and the second side surface of the write pole tip, wherein the shield is separated from the first side surface of the write pole tip by a first side gap, from the trailing surface of the write pole tip by a trailing gap, and from the second side surface of the write pole tip by a second side gap; and a first notch formed in an inner wall of the shield adjacent to a first corner of the write pole tip formed by the first side surface of the write pole tip and the trailing surface of the write pole tip, wherein the first side surface of the write pole tip comprises a first bottom portion arranged at a first angle from a normal to the leading surface of the write pole tip, and a first top portion arranged a second angle greater than the first angle from the normal to the leading surface of the write pole tip, and wherein the second side surface of the write pole tip comprises a second bottom portion arranged at the first angle from the normal to the leading surface of the write pole tip, and a second top portion arranged at the second angle from the normal to the leading surface of the write pole tip.
