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.
