I know that grades list.
Checking through all my info shows up the following.
companny grades and the grades in this list might not the same.
Let me go through the points.
Compatability with burners - Some drives hate some disc's.
a good disc might be burnt poor because of bad laser optimalisation. Everyone thinks that TY makes A-grade disc's but lets say My burner screws the disc up and it's measured back and it's absolutely not grade A. Does this mean that it may not be named grade A when sold to stores. What I am saying is quality is compatbility dependant !!
Compatbility with the reader- Since there are many different analyzers out there do we really think there all measureing the same. The more expensive calibrated drives will but it's a question if cheap analyzers like the clover, datarius or from CD Associates do. Also the measurement is speed dependant and some analyzers are used for fast cd testing. Which makes a difference.
So what I am thinking is that the quality grades in your signature are for the clover device. And have nothing to do with the internal factory grades.
Another point in this discussion.
MAM america states on there site that they put the best gold disc's asside and sell them these days as Archive Gold.
Now it is known that a lot of cd producers do this.
So why won't TY do this.
Some name them grade "A+"
others name them grade "S" (superior)
And most German stores seem to call TY's (A+) line grade E or grade E (A+)
So it might be that there distibutor came up with the E for the A+ or TY or the stores did it themselves. (In the last case they might have made a quite good conspiracy out of it )
Still I agree and it makes a odd one if you list them in the order compared to the others.
Another point is How do factories determine there grades ?
Should be testing however testing will cost a disc so they probally do it each X times. Now the question is how manny times X. And this X looks to be just depending on the quality procedure of the companny.
So what am I thinking.
I am thinking that factory grades are something different thing as the grades we have seen befor.
And I personally think that ther person who I spoke some time ago and said that it had to do with the stamper ussage might be closer than I first thought.
If this is true then it might also be true that TY is selling 2 quality ranges on there market.
Personally I first didn't believe it myself that TY has a 2 different ranges. However the results I have seen do show a slight difference in favor of the supposed grade E disc's.
Which actually made me know have some doubts about it.
Still this just could be the difference in batch quality !
The price difference is small with most of these stores. So we aren't ripped of. THe only webstore which sells there supposed
E graded TY disc's for a quite high price is the Feurio webstore.
(arround 60 euro's for 100 pieces)
I might pull some strings to find out what's the truth about it.
But if anyone knows more about it then let me know.
