| Research Abstract |
We have designed ultra fast and ultra high-density magnetic recording system using electromagnetic simulation. Our novel system is 100,000 times faster than conventional one and recording density is over 2Tbit/inch^2. The system consists of plasmonic cross antennas to generate the localized circularly polarized light and bit-patterned media to store information. Nano antennas were fabricated and we had a success of an experiment of ultra fast magnetic recording using a femto laser pulse.
