CMC DVD+/-R's technically there quite okay.
(THe verbatim -r I got look not as rough made as normal CMC material.
The laquer over the sides is done very clean not something you see much from CMC. I was a bit surprised that CMC could make so clean looking disc's)
However there is still one bad issue with these disc's. It looks like there is tension or air bubbles in some of the disc's innerhub (The see through part) while on no other part there are this bubbles this still is something I do not like.
Because of this construction errors the disc could scatter quite easy when they encounter very high (rotation) speeds.
About CMC and ageing. Well CMC is currently ussing a dye based on a mixture of Metalized Azo(MCC technology !) and Cyanine.(Just like most dvd manufacturers use !). Depending on more AZO it will be more stable (unless you have metal stabilized cyanine) but don't forget AZO is more as twice expensive to use as cyanine !
Just for some people there are some companies as Princo who use pure cyanine for DVD recording. And Princo really has a bad cyanine composition this explains the fast ageing and fast decomposition of the disc's
Now advanced ageing tests of CMC disc's showed that they were better as ritek g04 (Which quality seems more and more over rated these days !)Now the new 4x DVD+R ones are supposed to be based on a newer generation dye and are supposed to be more stable.
CMC is improving there quality overall still they produce way to much very bad disc's just like MBIL and Ritek. MBIL and CMC have less variance in the quality compared to Ritek but they also have less very good disc's.
So how do CMC disc's work. Well if CMC made them decent then the
Pioneer A06 can burn them quite decent.
Why prefer Ricoh even if they are less good constructed. Since Ricoh disc's seem to be a bit more rought overall made.
A Ricoh's dye has shown extreme good results in accelerated ageing tests. So it should be better for storage
B Ricoh's name !. Because it's Ricoh most manufacturers spent much more time on optimalisation and implementation the media. This why
Ricoh media will burn better even if it's less good manufactured.
C Speed some drives will let you write on Ricoh 4x media at 8x and some will even let you write not faster as 2.4x for the CMC disc's even while the burner can do 4x on other disc's.
