A relatively simple method for crystallizing the as-deposited amorphous chalcogenide coating on MYLAR* substrates is described. The process offers improvement over oven heating currently used to produce crystallization of the chalcogenide. Oven heating results in warpage, causing aerodynamic instabilities when the disk is spun.
