Abstract
A readout method to amplify the MO signal by using a magnetic domain expansion phenomenon have been proposed. It was found that the small MO signal reproduced from 0.08 micrometers crescent shaped domain was amplified 5 times larger than that of conventional disk without readout field. Also the reproduced signal level reaches to about 70% of the saturated signal amplitude. The result corresponds to 20 Gbit/in2 areal density with conventional 680 nm laser.
