Abstract
For higher density MO recording, a magnetic domain expansion readout m ethod named MAMMOS has been proposed [1]. Herein we report a novel MAM MOS scheme using an in-plane to perpendicular magnetization changing e ffect. Expansion readout has been achieved by both a magnetic field mo dulation method and a light intensity modulation method. A clearly amp lified readout signal was reproduced from.repetition of 0.2 mu m packe d marks.
