    摘要: A near field transducer antenna has a first end proximate a media writing surface and a second end proximate a waveguide that delivers light to the antenna. The antenna includes an aperture disposed along a propagation axis that extends from the first end to the second end. A notch protrudes within the aperture. The notch is facing an opening of the aperture that extends along the propagation axis. A magnetic pole is proximate the antenna, and includes a first portion of magnetic material and a second portion of antenna material. The second portion is disposed over the opening of the aperture and facing the notch of the antenna.
