[QUOTE=geno888;2149091]When developers write a firmware, they usually run some tests on the media, so if a firmware allow a disc to be burned at 20x, then developers was able to create a writing strategy that will not ruin discs.
But… too bad there is a rather wide variability in quality between various batch of media, so if you get a bad batch is better to not burn these discs at a so high speed, even if the firmware allow it.
As I said, the only way to see if is safe to burn a media at a speed higher than the certified speed is to try some discs and see results.
Don’t give too much importance to the maximum speed a drive can reach. Most of times, this is only advertisement crap :([/QUOTE]
Well, of coz. Juz that Troy512 sounded like burning at a drive’s maximum speed is not a good idea.
Besides, I already had 2 discs corrupted. Do u think it could be caused by burning the disc exceeding the stated maximum speed? Or by the sleeves? The sleeves seem to be sticking onto the discs like there’re water on it, which it doesn’t actually.
Btw, I’m using Mitsubishi DVD+R, which is a top graded discs inferior only to Taiyo Yuden. Do u think it can be burned at high speed?
& how do u see the results? Juz merely on whether it can be read? Or testing the burn quality?
[QUOTE=geno888;2149091]The main defects of plastic sleeves are two: they can scratch discs and they can warp discs.
If the sleeves are made good, however, (i.e. not too tight and provided with a material that will not scratch discs when you insert/extract media from the sleeve) they are a reasonable alternative to jewel cases :)[/QUOTE]
I see… Btw, I guess disc warping is external factor, right?
