Perpendicular magnetic recording head with a multilayered main write pole |
| 摘要 |
A perpendicular magnetic recording head includes a multilayered main write pole. The main write pole includes a first layer of material, a second layer of material, and an interlayer positioned between the first layer of material and the second layer of material. The second layer of material has a saturation magnetic moment greater than a saturation magnetic moment of the first layer of material.
