Perpendicular write head with high magnetization pole material and method of fabricating the write head |
摘要 |
A write head comprises a yoke including a top pole and a bottom pole, the top pole including a layer of insulating material, a layer of a first magnetic material positioned on a surface of the layer of insulating material, the first magnetic material having a first end positioned adjacent to an air bearing surface of the write pole, and a layer of a second magnetic material positioned on the surface of the layer of insulating material, the second magnetic material having a lower magnetic moment than the first magnetic material and being positioned to conduct magnetic flux between the return pole and the layer of first magnetic material. The method of constructing the write head and a disc drive including the write head are also included.
