Abstract
The present disclosure is generally related to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a main pole extending to a media facing surface (MFS). The main pole has a gradually increasing cross-section area with a low aspect ratio from the MFS to a surface recessed from and parallel to the MFS. The main pole comprises a first leading edge taper angle (LETA), a second LETA less than the first LETA, a first trailing edge taper angle (TETA), and a second TETA less than the first TETA. The main pole further comprises a first flare recessed a first distance from the MFS, the first flare having a first angle, and a second flare recessed a second distance from the MFS greater than the first distance, the second flare having a second angle greater than the first angle.
