摘要： In an example, a method comprises aligning a central axis of a paddle portion on a write pole circuit to be substantially perpendicular to an adjacent magnetic surface, and bending a central axis of an extended tip portion relative to the central axis of the paddle portion. In another example, a transducer head comprises a write pole circuit having a paddle portion with a central axis, and an extended tip portion with a central axis, the central axis of the extended tip portion angled from the central axis of the paddle portion. In another example, a magnetic circuit comprises a write pole circuit having a paddle portion and an extended tip portion, the extended tip portion bending away from a central axis of the paddle portion, and a coil wrapping around the extended tip portion.

摘要： 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.
