the dye defect is very visible at certain angles. but I had a hard time to take the photo, because at those angles the brightness is very low and the camera needs a long exposure… the photo gets blurred. I had to take the photo at ISO400 (thus the grain).
But with my eyes, the defect is very clear. It looks as if a drop of “dying liquid” had been accidentally dropped into the disc. The disc is otherwise a perfectly normal disc.
Also, it is noteworthy that, after burning the disc, the blemish became less apparent.
Regarding the cloud of dust (disc n.25), I haven’t tried to clean it yet. I guess I will be able to remove the dust, but they will leave some “micro-punctures” behind. When the disc has dust, and you put the disc in the stack, (very tight), the presure forces the dust against the plastic and you get punctures (permanent cloud).
Before doing any RMA (a hassle, and mailcosts), I would like to know if these issues (dye blemishes (drops), dust, fingerprints) are easy to find in all brands, or its just a matter of G04. Just imagine if I get a substitute and I find the same problem.
As I said before, I also got dust in a spindle of 25 Verbatim Pastels. I just have checked the first 3 discs on top. The first one had a lot of dust and is definitely punctured by the dust. I will burn this one soon. Maybe the quality is not affected. In contrast, the dye looks very smooth, as expected from TY.
Oh, a tip: always use halogen light to check for dust or fingerprints on the discs.
There are 5 discs left and until now i had one with a physical error that could be clearly seen.
does it look like a “raindrop” in the disc?
Note that the “drop” is very visible before burning the disc, but becomes somewhat concealed after burning. So it is better to check before.
It had a mayor error increase at that particular point
Yes, with Kprobe I also get a clear increase in PIF errors at the “drop” area. But still, the values are acceptable (PIF under 6, PI around 20)
I now use Taiyo Yuden 4x DVD-R only!
Did you finally order them at os-mediatrade?
are they ok? Do they have dust, fingerprints,…? Do they have low PI/PIF?
I checked os-mediatrade website and I saw those TY, but they look strange… with no brand printed anywhere in the spindle or the discs…
regarding Verb. Pastels, in this post:
I donÂ´t mean the Verbatim DLP Pastel discs though, but true (preferibly DVD-R) TY branded discs on spindles
did you mean that Verbatim Pastels are fake TYG01?
