Patent ID: 7768742

Claim:
A perpendicular recording write head in an intermediate stage of fabrication, comprising: a coil structure for producing a magnetic flux, the coil structure including an insulation stack for insulating coils, the coil structure further being located proximate to an air-bearing surface and extending toward a backgap; a pole, formed over the coil structure, having a first end recessed a predetermined distance from the air-bearing surface to form a recessed area between the first end and the air-bearing surface and having a second end joining the backgap, the pole extending over the coil structure between the first end and the second end for transferring the magnetic flux to the air-bearing surface; an isolative material formed in the recessed area between the first end of the pole and the air-bearing surface; a layer of heat-treated material disposed over the pole, the layer of material having a trench formed therein, the trench having a substantially trapezoidal shape with angled sides having a predetermined pullback angle for defining a trackwidth, wherein the layer of heat-treated material is a resist forming a damascene pullback trench; and a magnetic probe disposed in the trench of the layer of heat-treated material and forming a probetip extending to the air-bearing surface, the magnetic probe assuming the substantially trapezoidal shape of the trench, wherein opposite parallel sides of the magnetic probe have a first length and a second length, the first length being longer than the second length, wherein the second length is configured to maintain a position in a shadow of the first length as the substantially trapezoidal-shaped magnetic probe is skewed from an inner diameter to an outer diameter of a magnetic recording medium.
