摘要： A magnetic transducing head having an air bearing surface has a bottom shield, a shared pole, a read element, a substantially planar composite top pole; and a conductive coil. The read element is positioned between the bottom shield and the shared pole. The top pole is formed of high magnetic moment pole tip portion and a high resistivity yoke portion. The pole tip portion of the top pole is substantially coplanar with the yoke portion of the top pole. The pole tip portion of the top pole is separated from the shared pole at the air bearing surface by a write gap, while the yoke portion of the top pole is in contact with the shared pole opposite the air bearing surface. At least a portion of the conductive coil is positioned between the shared pole and the top pole.

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 magnetic recording head has a top pole, a write gap layer, a shared pole, and conductive coils. The shared pole has an air bearing surface, a top surface substantially normal to the air bearing surface, and a recess in the top surface extending across the top surface parallel to the air bearing surface. The shared pole is separated from the top pole at the air bearing surface by the write gap layer, and directly contacts the top pole at a region of the writer distal from the air bearing surface. Wrapped around the top pole are the conductive coils, a portion of which is positioned in the recess of the shared pole between the top pole and the shared pole.

摘要： A magnetic device includes a write element including a write element tip, and a conductive coil for carrying a write current to induce a first field in the write element. A first conductor proximate a trailing edge of the write pole tip is operable to carry a first assist current to generate a second field that augments the first field. A second conductor proximate a leading edge of the write pole tip is operable to carry a second assist current to generate a third field that augments the first field. First and second side shields are on opposing sides of the write element in a cross-track direction.

摘要： A write head for use in a magnetic disk drive and methods of manufacturing the same. When a non-magnetic reactive ion etching (RIE) stop layer is used in a damascene main pole fabrication process, the leading edge shield and the side shield have a magnetic separation. By replacing a non-magnetic RIE stop layer with a magnetic RIE stop layer, no removal of the RIE stop layer around the main pole is necessary. Additionally, the leading edge shield and the side shield will magnetically join together without extra processing as there will be no magnetic separation between the leading edge shield and the side shield.
摘要翻译：用于磁盘驱动器的写入头及其制造方法。当在非镶嵌主极制造工艺中使用非磁性反应离子蚀刻（RIE）停止层时，前缘屏蔽和侧面屏蔽层具有磁分离。通过用磁RIE停止层代替非磁性RIE停止层，不需要在主极周围去除RIE停止层。此外，前缘屏蔽和侧屏蔽将磁性地结合在一起而不需要额外的处理，因为前缘屏蔽和侧屏蔽之间将不会有磁性分离。
