A write head structure for perpendicular recording having a pole tip
integrated into the metal film surrounding a C aperture near field light
source is disclosed. The close proximity of the pole tip to the light
source enables more precise location of data cells written into the
magnetic media, through the use of dual gradient thermally assisted
recording. In dual gradient recording, data is fixed by the effect of
both a thermal gradient, which affects the coercivity of the magnetic
media, combined with a magnetic field gradient imposed by the pole tip.
