Abstract

For higher density MO recording, a magnetic domain expansion readout method named MAMMOS has been proposed [1]. Herein we report a novel MAMMOS scheme using an in-plane to perpendicular magnetization changing effect. Expansion readout has been achieved by both a magnetic field modulation method and a light intensity modulation method. A clearly amplified readout signal was reproduced from repetition of 0.2 [Mu] m packed marks.
