Abstract
A magnetic write head having a write pole with a tapered trailing edge and a magnetic oscillator formed on the trailing edge of the write pole. The magnetic oscillator is sandwiched between the magnetic write pole and a trailing magnetic shield. The write head also includes a non-magnetic, electrically conductive bump structure located over a back portion of the magnetic oscillator between the magnetic oscillator and the trailing magnetic shield. The presence of the non-magnetic, electrically conductive bump structure causes electrons to properly flow through the magnetic oscillator in a direction that is generally perpendicular to the plane of the magnetic oscillator, even when the magnetic oscillator is formed on an inclined plane on the tapered trailing edge of the write pole. This thereby ensures optimal performance of the magnetic oscillator.
