Abstract:
A near field transducer (NFT) that includes a disk, the disk having a top surface, a side surface, and a center; a peg, the peg positioned adjacent the side surface of the disk; and a heat sink, the heat sink positioned on the top surface of the disk, and the heat sink having an effective center, wherein the NFT has a peg axis, which is defined by the location of the peg adjacent the side surface of the disk, and a non-peg axis, which is perpendicular to the peg axis, and wherein the effective center of the heat sink is positioned at about the center of the disk.
