Abstract:
A TAMR head is disclosed with a hybrid plasmon generator (hPG) formed between a waveguide and write pole at an ABS. The hPG has a planar bottom surface facing the waveguide and is comprised of a first non-noble metal layer with a peg portion adjoining the ABS. The peg tip has a thickness in a down track direction and a width in a cross track direction that may be reduced to about 10 nm to shrink the size of the optical spot that provides localized heating to a track and facilitates the write process. A second metal layer made of a noble metal is formed on and alongside the first metal layer and is recessed from the ABS to expose the peg, and has a top surface adjoining the write pole that may have side and top heat sinks.
