About datasafe and ridisc and some other brands with MCC, FUJIFILM, TDK code.
This media most times is made under licens by CMC/Prodisc.
Now about the quality there is no guarantee that the quality will be good unlike the retail products of the brands.
Is there a guarantee for the retail products some people would ask.
Well there is.
If Fuji, TDK, Mitsubishi/Verbatim media is bad then the media will be replaced.
Specially verbatim is very tollerant when it comes to replaceing there media.
In this case with these smaller brands there is no such guarantee.
Also the variation in quality is higher for these B brands.
But still these B brands can be just as good or bad as verbatim or any of the other brands !!
So should we leave them alone ?
Hmm that depends. Most times the media is quite decent. (Infact price quality ratio is most times excellent.)
However if you want to be sure that you get good media you will be better of with the real branded stuff.(Verbatim/FUJI/TDK) (From TDK and Verbatim it is known that they have extra quality controle for all there own media !)
