    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 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.
