Estimating the term…
A first trench sidewall has a continuous first taper angle that terminates at a first plane. At least one layer may be deposited that forms a second trench sidewall with a continuous second taper angle that extends a predetermined depth past the first plane and is less than the first taper angle. A write pole may then be formed on the second trench sidewall with the write pole being closer to the first trench sidewall at the predetermined depth than at the first plane.
An apparatus comprising a write pole with a first sidewall having a continuous first taper angle that extends a predetermined depth past a first plane and adjacent a first trench sidewall having a continuous second taper angle, the first taper angle being less than the second taper angle, and at least one layer of non-magnetic material that continuously coats the first trench sidewall to transition from the second taper angle to the first taper angle.
A method comprising:
14-15. (canceled)
(canceled)
A method comprising providing a first trench sidewall having continuous first taper angle that terminates at a first plane and depositing at least one layer onto the first trench sidewall to create a second trench sidewall that has a continuous second taper angle that extends farther from the first trench sidewall at the first plane than at a predetermined depth from the first plane.
