Well, tonight I went and bought a cakebox of 50 Fuji Taiyo Yudens 48x rated in the normal older non-colored tops based on the glowing reviews of this media… It is good media. But it’s not the best.
Disc Type, Material = CD-R, Cyanine
ATIP Lead-in = 97m 24s 01f
Norminal Capacity = 702.83MB (79m 59s 72f)
Disc Manufacturer maybe = Taiyoyuden,DX Dye
SMART-BURN Speed Limit = 52X
I have saved all my results as PNGs but to save bandwidth I thought I’d type them in. 703 meg images. All reads at MAX speed. All burns done on 52246S 6S0F writer.
52x- write failure, disc was on top of cakebox.
52x try 2- this was after 2 more burns
C1 Max=15 Total=5179 Avg=1.226
C2 Max=26 Total=26 Avg=0.006
48x- smart burn activated at the very end of the disc since I saw a yellow light go on. Didn’t bother with another try.
C1 Max=12 Total=2525 Avg=0.596
C1 Max=7 Total=740 Avg=0.175
C1 Max=7 Total=775 Avg=0.183
C1 Max=8 Total=1097 Avg=0.259
We can see here why rdgrimes recommends 40x as a write speed. It is the sweet spot with this media on this writer with this firmware.
Now as to my statement why I think it’s overrated. Well, my two experiments previously on two other cds with the exact same image:
Verbatim 48x rated burned at 52x-
C1 Max=17 Total=1685 Avg=0.403
Liteon (Ritek TG) burned at 52x-
C1 Max=18 Total=1275 Avg=0.307
C2 Max=1 Total=2 Avg=0.000
Given that the average of both the Verbatim (Super Azo) and the Liteon (Ritek TG Phthalocyanine) are BOTH lower at 52x than the cyanine Taiyo Yudens were at 48x one can easily postulate that at lower speeds both those mediadyes will get better results in comparison with TY’s DX. Smartburn wasn’t required for either of those also.
And there you have it.
