Split-ring resonator (SRR) NFT design for use in HAMR
Abstract:
An NFT is used in a HAMR magnetic write head. The NFT functions as a resonant circuit when in operation. The resonant circuit, which comprises the NFT, is a split-ring resonator (SRR) that has a capacitive portion and an inductive portion. The inductance and the capacitance results in a very well focused ultra-small spot-size concentrated on the magnetic media. The focus occurs at the capacitive area of the NFT with minimal to no impact upon the write pole of the HAMR magnetic head.
