Patent ID: 8724259

Claim:
A recording transducer for use in a data storage device, the recording transducer comprising a magnetic writer pole, the magnetic writer pole having a pole tip facing an air bearing surface (ABS); the pole tip comprising a pole face, leading side wall, a trailing side wall, a first side wall and a second side wall; the recording transducer further comprising: a trailing side wall nonmagnetic gap layer deposited on the trailing side wall, a first side wall nonmagnetic gap layer deposited on the first side wall, and a second side wall nonmagnetic gap layer deposited on the second side wall, a first portion of the trailing side wall nonmagnetic gap layer being conformal with the trailing side wall and extending from the ABS; a trailing seed layer comprising a first magnetic material, a first portion of the trailing seed layer extending from the ABS, deposited on a second portion of the trailing side wall nonmagnetic gap layer, being conformal with the trailing side wall nonmagnetic gap layer and being conformal with the trailing side wall, a second portion of the trailing seed layer being recessed from the ABS, adjacent to the first portion of the trailing seed layer, nonconformal with portion of the trailing sidewall nonmagnetic gap layer and nonconformal with the trailing side wall; a first side seed layer comprising the first magnetic material deposited on the first side wall nonmagnetic gap layer, and a second side seed layer comprising the first magnetic material deposited on the second side wall nonmagnetic gap layer; wherein the first magnetic material has a magnetic moment (B s ) between 2.0 T and 2.4 T.
