Analysis of Plasmonic Beak Antennas for All-Optical Magnetic Recording -Electric Field Intensity in Recording Media by Changing Beak Shape

摘要

For ultra-high speed and high density recording, all-optical magnetic recording with circularly polarized light and bit-patterned media technology are attracted attentions. We reported that localized circular polarization could generate in the medium from a linearly polarized incident light. In this paper, characteristics of plasmonic beak antennas with bit-patterned media are investigated and the effect on the intensity by changing a beak shape is discussed.
