Abstract :
A readout method to amplify the MO signal by using a magnetic domain expansion phenomenon has been proposed and results shown. It was found that the small MO signal reproduced from the small recorded domain was amplified. This novel magnetic domain expansion read out technique shows high promise for future data storage technology.
