Abstract: A magnetic recording head comprises a write pole having a tip adjacent to an air bearing surface of the recording head, a return pole magnetically coupled to the write pole, a conductor positioned adjacent to at least one edge of the write pole at the air bearing surface for carrying current to produce a magnetic field that saturates at least a portion of the write pole and augments a write field, a first conductive heat sink connected to a first end of the conductor, and a second conductive heat sink connected to a second end of the conductor. Disc drives that include the recording head are also included.

Abstract: A magnetic head for generating a magnetic field is provided in which first and second electrical contacts are electrically coupled to a thin film wire. An electrical current is passed between the contacts and through the wire to generate a magnetic field. A focus mechanism is provided to focus the magnetic field and thereby increase the flux density of the magnetic field along a recording edge of the thin film wire.

Abstract: A single pole magnetic recording head is provided according to the present invention for perpendicular magnetic recording on a recording medium. The magnetic recording head includes a main magnetic pole and a coil magnetically coupled to the main pole for magnetizing the main pole in a first magnetization direction. The magnetic recording head further includes a layer of ferromagnetic material anti-ferromagnetically coupled to the main pole such that magnetization of the ferromagnetic layer is in a second magnetization direction substantially anti-parallel to the first magnetization direction of the main pole.
