摘要: A magnetic writing pole writes perpendicularly to a magnetic medium. The writing pole includes a multilayer structure with alternately electroplated magnetic layers and electroplated non-magnetic layers. The writing pole has a down-track thickness near the magnetic medium of less than about 500 nm.
摘要翻译: 磁写字柱垂直写入磁介质。 书写杆包括具有交替电镀的磁性层和电镀非磁性层的多层结构。 写磁极在磁介质附近具有小于约500nm的下轨道厚度。

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.
