Well only Verbatim pastel cd-r's are Taiyo Yuden.
And Datalife Plus should still mean made with MCC licensced AZO Technology.
The rest could have codes from any manufacturer from which MCC has done bussiness with.(CMC, MBIL, PRODISC)
CHINA => CMC.
I would return these since there looks to be a sing of vissible defects. (the rings.) or you could contact verbatim and see what you can work out with them. Most times Verbatim has quite good support.
Let me say this I won't use any Verbatim disc's which are not made with MCC technology or are made by TY because the others don't have a good reputation.
Reorder number you probally want is:43418 (that's the pastel version which so far allways has been TY)
For a good adress in Holland/Belgium check.:
. com 24.90 euro /100 pieces. (price was lowered so I corrected it !)
Which seems to be one of the cheaper stores.
They can guarantee you that you will get Taiyo Yuden Verbatim disc's.
Price might be higher as you paid for these. But then again you have the guarantee that these are TY's. Also if you want CMC media then you can allways go for the cheaper Philips spindles at cdrwinkel for 25 pcs for 5 euro's)
