I've already had that problem on crappy MAM-E DVD-R 4X media(MCI4XG01) and over time the spikes were getting longer and longer, the data on the outter edges becoming unreadable after a few years
in the mean time I bought some MAM-E DVD-R 8X(TTH01), that had VERY low PI/PO rates on my Pioneer DVR108, yet some of them also had spikes in the metalizing layer on the outter edges.
yet, after 3 years they still seem fully readable
since then, I've also seen the problem on Verbatim DVD-R 8X(TYG02) made by Taiyo....
and now I'm also encountering it on some recent Verbatim DVD-R 16X(MCC03RG20) made by CMC(hub code starts by MAP...), I've never had this problem on MCC-made MCC03RG20
here's some photos from the top, I wasn't able to take photos from the recordable side...it wouldn't show because of all the reflections.
at some point I spoke about that problem to the Product Manager of MAM-E, and he told me these spikes did not reach the data portion, and only an unstable dye could "kill" the data(ie. their old MCI4XG01), not spikes in the metalizing layer.
but some of the spikes clearly make it to the data portion on these CMC Verb
what do you guys think ?
I'm kinda P%SSED OFF that even Verbatim has these issues :a
these CMC-made Verbatim discs are dirt cheap, but it shows!
and because MCC and CMC can't be recognized from the outside(MIT), then I'm screwed! :o
I've seen the same thing on TDK +R media too(MAM-E made ?)
Thanks for any insight,
