Method and system for providing a magnetic transducer having a high moment bilayer magnetic seed layer for a trailing shield

A magnetic recording disk drive comprising:

• a media;
• a slider;
• a magnetic transducer coupled with the slider and having an air-bearing surface (ABS) configured to reside in proximity to the media during operation, the magnetic transducer including a write pole, a nonmagnetic gap, a magnetic seed layer, a trailing shield, and at least one coil, the write pole configured to write to the media, the magnetic seed layer including a high moment layer and a magnetic buffer layer, the high moment layer being between the nonmagnetic gap and the magnetic buffer layer, the nonmagnetic gap being between the magnetic seed layer and the write pole, the high moment layer having a saturation magnetization greater than 2.3 T and a first corrosion potential, the magnetic buffer layer having a second corrosion potential less than the first corrosion potential, the magnetic seed layer being between the trailing shield and the nonmagnetic gap layer, the magnetic buffer layer being between the trailing shield and the high moment layer, the at least one coil for energizing the write pole.
