面内磁化再生層を用いた静磁結合型MAMMOS媒体　∼DC光DC磁界による磁区拡大再生∼

抄録

A new scheme called MAMMOS for magnetic expansion readout MO is introduced with the aim of achieving high-density recording. A magnetic expansion phenomenon was observed in a magneto-static coupled-type medium with an in-plane magnetization readout layer using dc laser power and a dc magnetic field in the readout process. By taking advantage of this unique expansion phenomenon, it is possible to resolve 0.22 μm domains and to obtain a clear signal in new MAMMOS media.
