| This test aims to examine the UV Resistance of DVD-R. As known, ultraviolet ray(UV) contained in sunlight kills dye and recorded data. Then, if we expose DVD-R recording surface to direct sunlight? Data crashed at once? or slowly spending several weeks? Now I test on 26 disks....... TY, maxell, Verbatim, RiTEK, CMC, SONY......and others. Test the product of which manufacturer has strong resistance to UV. |

*Verbatim
Advanced-AZO is the best UV stability.
*16X media are inferior to 8X media by
UV stability.
*MCC Advanced-AZO＞other AZO＞UV Protected Cyanine＞FUJI
OXOLIFE＞Cheap Cyanine
*DoubleLayer disc is not greatly inferior to
SingleLayer one in UV stability.
