I got 200 of these about a month back. Burned about 50 of these and have mixed feelings - some discs burned excellent with less than 100 PIFs and quality score of 98/99. But most discs showed clusters of errors with total PIFs around 3000 and a quality score of 93 to 97 - quite ‘good’ by itself, but not ‘excellent’ as I expected from TY media. And a few (i guess about 4 in the 50 I burnt) were really bad with scores of less than 80.
Don’t know if the variability is in the media or my burner (BenQ 1640). See my post about burning TYG01 in the BenQ forum. I paid about 24 cents for each disc, and I think they are OK for the price, but I really expected better quality.
I contacted shop4tech, but they were of not much help. They were ready to take the discs back and refund me, but the return shipping made it a bad deal for me and I decided to keep the media.
Based on the feedback I got on the BenQ forums, here is my conclusion - these “value” TYG01s are really old stock. They must’ve been lying in some warehouse for quite sometime now - most likely on their side. The recording layer dye has deteriorated a bit (bad storage conditions??) and every disc has some patches/clusters or bad-dye spots which is causing it to have sudden peaks and error clusters while the rest of the disc burns super-fine. I’ve tried every possible option from write-start swapping, different firmware versions, different speeds, different burners (NEC-2510 and LiteOn 813s) but failed to get consitent burns from the media.
Some people have reported that they ordered the TYG01, but recieved the TYG02s instead. If you believe you are lucky, you can order and see what you get. But, if I were to buy again, I’d pay the extra 6 or 7cents per disc and get the TYG02s.
