The pole tip occupies part of the MFS. The yoke has a yoke length measured from the MFS in a yoke direction perpendicular to the MFS. The yoke length is less than four microns. The main pole has a total length in the yoke direction and a width in a cross-track direction. The main pole is continuous along the total length. The aspect ratio of the main pole is the total length divided by the width and exceeds one. The main pole includes surface(s) having a nonzero acute flare angle from the MFS. The auxiliary pole is adjacent to the main pole and recessed from the MFS by not more than 1.05 micron. The coil(s) energizes the main pole and have not more than two turns."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic recording write apparatus having a pole having an aspect ratio greater than one and an auxiliary pole","description":"A magnetic write apparatus has a media-facing surface (MFS) and includes an auxiliary pole, coil(s) and a main pole having a pole tip and a yoke.
