A microwave assisted magnetic recording system includes a write pole that
generates a write magnetic field, an element that generates a radio
frequency assist magnetic field, and a recording medium that moves
relative to the write pole. The recording medium is exposed to the radio
frequency assist magnetic field before it is exposed to the write
magnetic field. One possible element that generates the radio frequency
assist magnetic field is an assist wire placed perpendicular to the write
pole. Alternatively, the assist wire can be placed parallel to the write
pole so that its radio frequency assist magnetic field couples with the
write pole, which in turn generates its own coupled radio frequency
magnetic field along with the write magnetic field.
