Method and system for providing a magnetic transducer having a high moment bilayer magnetic seed layer for a trailing shield |
摘要 |
A method and system for providing a magnetic read transducer is described. The magnetic recording transducer includes a write pole, a nonmagnetic gap, a magnetic seed layer, a trailing shield and coil(s) that energize the write pole. The write pole is configured to write to a media. The nonmagnetic gap is between the write pole and the magnetic seed layer. The magnetic seed layer includes a high moment layer and a magnetic buffer layer. The high moment layer is between the nonmagnetic gap and the magnetic buffer layer. The high moment layer has a saturation magnetization greater than 2.3 T and a first corrosion potential. The magnetic buffer layer has a second corrosion potential less than the first corrosion potential. The magnetic seed layer is between the trailing shield and the nonmagnetic gap layer. The magnetic buffer layer is between the trailing shield and the high moment layer. |
