    摘要： A magnetic recording head having an air bearing surface for confronting a surface of a rotating disc and comprising a pole tip and a generally rounded and substantially planar body attached to the pole tip is disclosed. The width of the pole tip defines a track width of data written to the rotating disc. The generally rounded shape of the top pole body is such that top pole magnetization gradually changes its direction and follows the edges of the body. Further, the pole tip has low remanence, gradual spin structure and no domain walls formed near the pole tip.

    摘要： A magnetic writer having an air bearing surface for confronting a surface of a rotating disc is disclosed. The magnetic writer includes a bottom pole and a top pole. The top pole includes a first top pole portion and a second top pole portion connected by a top pole extension. The top pole extension, which preferably has a uniform width at the air bearing surface, orients a magnetization of the first top pole portion substantially parallel to an air bearing surface of the magnetic writer. The bottom pole includes a base pole and a notch pole. The base pole is recessed from the air bearing surface to prevent or reduce fringe erasure fields. The notch pole, which abuts the base pole and extends from the air bearing surface to at least a magnetic throat height of the magnetic writer, has a magnetization oriented perpendicular to the air bearing surface.

    摘要： A magnetic head in a magnetic storage system is provided in which materials that do not individually display high permeability and low coercivity are satisfactorily employed in a write head when coupled to adjacent high permeability layers. The magnetic head includes a gap layer which separates a pair of poles. At least one pole of the pair of poles includes a pole layer formed of a high permeability material and a seed layer adjacent to the pole layer. The seed layer is formed of a high moment low permeability material having a high saturation magnetic moment greater than 2.1 Tesla and a low permeability of about 10-100. The high permeability material of the pole layer causes the permeability of the adjacent seed layer to substantially increase from about 10-100 to about 1400-1600, thereby providing a pole with high permeability and high saturation moment. In addition, a method of forming a magnetic head for use in a magnetic storage system is provided.
