Abstract
Disclosed is an MR head, and the method of making the same, which has a pole/shield. In the preferred embodiment, the pole side of the pole/shield is constructed such that it has a length that is approximately equal to the length of the pole, and a shield side that is approximately the length of a shield. Through this construction, the MR element, which is disposed between the shield side and the shield, is fully shielded during a read operation. Additionally, the flux lines generated during a write operation approximate the length of the pole so that excessive fringing does not occur. As a result of the smaller flux lines generated between the pole and the pole side of the pole/shield, data may be more densely packed on the disk used in conjunction with the MR head.
