The magnetic recording device comprises a main pole disposed at a media facing surface (MFS), a trailing shield disposed adjacent to the main pole, and a trailing gap disposed between the main pole and the trailing shield. The trailing shield comprises a hot seed layer disposed adjacent to the trailing gap, and a notch comprising a −Ku material in contact with the hot seed layer and the trailing gap. The notch is disposed adjacent to a first surface of the main pole at the MFS. The notch comprising the −Ku material results in an increased effective write magnetic field, an increased down-track field gradient due to reduced shunting from the main pole to the trailing shield, leading to an increased areal density capacity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Area density capacity improvement with negative anisotropic magnetic material trailing shield notch","description":"Embodiments of the present disclosure generally relate to a magnetic recording device comprising a magnetic recording head having a negative anisotropic magnetic (−Ku) material notch.
