摘要：
In a heat-assisted magnetic recording head for use in a hard disk drive, a thermal shunt is positioned between an E-antenna near field transducer (NFT) and a return pole, to draw excess heat away from the NFT region. The thermal shunt comprises two portions separated by a gap that has a trapezoidal cross-section, where the NFT-side of the gap is wider than the return pole-side of the gap.
