Claim:
1. A method comprising: forming a write pole with a tip portion that continuously extends from an air bearing surface (ABS) along a plane orthogonal to the ABS to a body portion that continuously extends from the tip portion distal the ABS; depositing a first write gap layer in contact with the write pole; depositing a processing layer in contact with the first write gap layer; creating a second write gap layer in contact with the processing layer; and forming a magnetic shield atop the processing layer at the ABS and atop the second write gap layer distal the ABS, the magnetic shield separated from the write pole by a first gap distance on the ABS throughout the tip portion, by a second gap distance distal the ABS, and by a third gap distance distal the ABS, the first, second, and third gap distances each measured parallel to the ABS from a write pole sidewall to the magnetic shield with the second gap distance being greater than the first gap distance and the third gap distance being greater than the respective first and second gap distances, the first gap distance connected to the second gap distance with a transition sidewall of the magnetic shield having a continuously curvilinear surface that has a shape dissimilar from any portion of the write pole sidewall, the transition sidewall separating the second write gap layer from the ABS.
