Abstract
The present disclosure is generally related to a magnetic recording device comprising a magnetic recording head having a first current flow in a cross-track direction through a trailing shield. In one or more embodiments, a second current flows in a cross-track direction around the main pole. The magnetic recording device comprises a main pole disposed between a trailing shield, a leading shield, and side shields. A trailing gap is disposed between the side shields and the trailing shield. A high moment seed layer is disposed between the main pole and the trailing shield. A first insulation layer is disposed within the trailing shield and directs the first current through the trailing shield, guided to the proximity of the main pole. A second insulation layer, disposed below the trailing shield, directs the second current through the trailing shield, or alternatively through the side shields and around the main pole.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
