Abstract
Magneto-Optical (MO) disk possesses a very high advantage of high density recording compared to non magnetic optical disk, because MO recording is almost same as a perpendicular magnetic recording However, the high density recording is recorded by very tiny domains, so the readout MO signal decreases and the correct data reproduction becomes impossible. In order to amplify the small MO signal, one new idea has been proposed.
