Abstract :
All optical magnetic recording with circularly polarized light has been studied for developing ultra-high speed recording. An asymmetric cross antenna, constituted by two perpendicular dipole antennas of different length, is investigated to generate localized circularly polarization in recording medium from linearly polarized incident light.
