摘要：

An advanced readout technique on using a dynamic domain expansion phenomenon has been proposed and investigated. Very small domains of 0.08 mu m which achieve an areal density of 20Gb/in(2) (CD single side 30GB with 680nm laser) expand during readout, causing the readout signal to increase to the same level as for 0.6 mu m domain.
