Dyan CD-RW disc are made by Ritek. I haven't used Dyan branded CD-RW disc before, but I know the Ritek CD-RW discs that I have used before are pretty good and reliable.
I had a few Dysan CD-R's - they are a subsiderary of Memorex and use the same companies. The last ones I bought were made by Prodisc but I think CMC made them too.
Dysan are still going? Wow, I haven't seen their media in a LONG time. But yes, anything that applies to Memtek applies to Dysan as they are one and the same.
BTW anyone know why Memorex don't use SKC CDR media? They've had a long, fruitful relationship with them with audio and video tapes, and you'd have thought SKC would have been the logical choice.
last time i bought dysan cdr's back in 1999, the label on top would chip off like confetti. Are they any better these days? The hi-val cdr's do that now.
