    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 writer includes a write element and an oscillation device disposed adjacent to the write element. The first oscillation device includes a first magnetic layer, a second magnetic layer having a magnetization vector including a component perpendicular to a major plane of the first magnetic layer. The first nonmagnetic layer disposed between the first magnetic layer and the second magnetic layer. The first oscillation device generates a high-frequency oscillation field when a current is directed perpendicular to the major plane of the first magnetic layer.

    摘要： A magnetic sensor is provided. The magnetic sensor includes a magnetoresistive multi-layered portion that has a first resistance region and a second resistance region. At least two contacts are coupled to the magnetoresistive multi-layered portion. A sensing current flows from a first contact of the at least two contacts to a second contact of the at least two contacts via the first resistance region and the second resistance region of the magnetoresistive multi-layered portion. The first resistance region promotes a primary flow of the sensing current in a first direction substantially perpendicular to surface planes of the layers of the magnetoresistive multi-layered portion, and the second resistance region promotes the primary flow of the sensing current in a second direction substantially in parallel to surface planes of the layers of the magnetoresistive multi-layered portion.
