I read the reviews of the 4x value lines at supermediastore and these are some of the comments I read
Defects, defects, defects…
Like the reviewer below that complains about the dye streak defect, I too have this problem in these 4x ‘value line’ discs. It is verrrrry hard to detect these streaking lines. Sometimes you have to be under bright lighting, and inspect the disc really well in various angles to find it. If you give it a quick once over, you’ll miss it. Too many of these discs have this problem. It’s like every other disc or 10 discs in a row will have it, then a few will be clean, and then another and another. It’s a very bad ratio of actual good discs vs defective discs. Sometimes I’d do a full inspection before I burn, only to see it visible upon further inspection after a burn. I’d run a quick PIE-PIF test on it and see it go crazy on the section of the dye bleeds. I am so sick of having to inspect every damn disc for 2 minutes before I insert in my burner. For the prices and reputation Taiyo Yuden has, this is UNACCEPTABLE. TY is touted as being one of the best, if not the best in the market, yet we get these faulty discs under these premium charges. For every bad TY disc I have, I put it in a seperate spindle to identify them, and I have STACKS of them. I am NEVER buying any more TYG01’s.
Not so good
I bought 6 100pks of these during the summer. I just opened my 3rd shrinkwrap of this and I’m not happy at all. It seems many of these discs are defective. Many of my discs have a dye bleed. I don’t know how to explain it but theres like a thin line of lighter purple that streaks across the dye of the disc. It appears in random spots on random discs. Sometimes you won’t even be able to see it. Many of my first 100pk has this, not so many on the 2nd, and many more on my 3rd. I still have 300 left unopened. I burned many important things on these defective discs. I’m very upset. I’m not the only one. http://club.cdfreaks.com/showthread.php?t=151948&highlight=taiyo+yuden+defect
So now being all paranoid, I started checking my G01’s and find this same shit. what the hell!
