Abstract
A recording head includes a near-field transducer configured to heat one or more portions of a magnetic storage layer to generate a thermal profile in the magnetic storage layer. The recording head includes a write pole configured to generate a magnetization pattern, in the magnetic storage layer, that overlaps with the thermal profile in the magnetic storage layer. The write pole includes a non-uniform surface that faces the magnetic storage layer, the non-uniform surface configured to cause a portion of the magnetization pattern to be approximately linear.
