Abstract :
In order to increase recording density, mark length recording is superior to mark position recording. However, in the case of magnetooptical media it is difficult to control mark edge position and shape because of its higher thermal conductivity. A new write control method using the multiple pulse write waveform is proposed, and it is shown that high density of 880 Mb/in2 can be realized using this write control method
