Abstract
The authors demonstrate a rapid and convenient method for the determination of writing and erasing laser powers in phase-change media based on scanning surface potential microscopy using a conductive tip. Commercially available digital versatile disks that are rewritable with initialization process are measured in experiments. The results of measurement show that when the disk is rotating at 3.5 ms linear velocity, the adequate writing and erasing of laser power are 10-15 and 4-8 mW, respectively. The critical laser power for crystallization conversion is 8 mW. The method used for this research can be satisfyingly applied to the development of new phase-change recording materials. © 2006 American Vacuum Society.
