摘要： A transducing head has a main pole and at least one magnetic element (such as a return pole or a shield) which provides a potential return path for a magnetic field produced by the main pole. The magnetic element is spaced from the main pole. The magnetic element is formed at least in part of a magnetic material having a material property that reduces side writing at the magnetic element.

摘要： A transducing head has a main pole and at least one magnetic element (such as a return pole or a shield) which provides a potential return path for a magnetic field produced by the main pole. The magnetic element is spaced from the main pole. The magnetic element has a first edge closest to the main pole and a second edge furthest from the main pole. Permeability of the magnetic element increases from the first edge to the second edge.

摘要： A transducing head has a main pole and at least one magnetic element (such as a return pole or a shield) which provides a potential return path for a magnetic field produced by the main pole. The magnetic element is spaced from the main pole. The magnetic element has a first edge closest to the main pole and a second edge furthest from the main pole. Permeability of the magnetic element increases from the first edge to the second edge.

摘要： A method of fabricating a recording head includes depositing an insulator material onto at least a portion of a first member, wherein the insulator material forms an insulator film having a film thickness. The method further includes depositing a writer pole material onto the insulator film, wherein the writer pole material forms a writer pole member, and wherein the insulator film is between the writer pole member and a contact layer. Further, in some embodiments, the film thickness determines the distance between the writer pole member and the first contact member and also determines the distance between the writer pole member and the second contact member.
