The pole includes a yoke extension, a yoke between the yoke extension and the MFS, and a pole tip between the yoke and the MFS. The write gap is between the top shield and the pole tip. The back gap is recessed from the ABS and magnetically and physically connects the top shield to the yoke. The coil(s) energize the pole and have multiple turns. Part of a first turn is between the yoke and the top shield. Part of a second turn is recessed from the MFS and aligned with part of the yoke extension. Part of the first turn is between the part of the second turn and the MFS. The back gap is between part of the first turn and part of the second turn."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Short yoke length writer having assist coils","description":"A magnetic apparatus has a media-facing surface (MFS), a pole, a top shield, a back gap and coil(s).
