Abstract
An amplified magneto-optical signal readout by using a dynamic domain expansion effect has been proposed and experimentally confirmed. Small domains of around 0.3 mu m in diameter were expanded by a pulsed exte rnal field on the readout layer copied from the recording layer. An am plified readout signal up to three times larger than that of the origi nal one has been achieved. (C) 1996 American Institute of Physics.
