Patent ID: 8411390

Claim:
A perpendicular head comprising: a pole layer, said pole layer having a flare point; a main coil, said main coil having a plurality of turns operable to affect the magnetization state of said pole layer; 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, said first conductive element being displaced a first distance from said pole layer, said first distance being measured from said pole layer to said first conductive element at the air bearing surface; 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, said second conductive element being displaced a second distance from said pole layer, said second distance being measured from said pole layer to said second conductive element at the air bearing surface; wherein said first distance is greater than said second distance.
