Patent ID: 8638527

Claim:
A method for writing data signals with a perpendicular head comprising: providing a perpendicular head having a pole layer, said pole layer having a flare point, a main coil, an auxiliary half coil, extending around three sides of said pole layer at an air bearing surface, said auxiliary half coil having a first terminating end and a second terminating end, a first conductive element coupled to said first terminating end of said auxiliary half coil, said first conductive element extending from said air bearing surface, approximately perpendicular to said air bearing surface, to beyond said flare point of said pole layer, and a second conductive element coupled to said second terminating end of said auxiliary half coil, said second conductive element extending from said air bearing surface, approximately perpendicular to said air bearing surface, to beyond said flare point of said pole layer; providing a data signal current to said main coil; and providing a differential high frequency signal current, said differential high frequency signal current flowing through said first conductive element, through said second conductive element, and through said auxiliary half coil.
