The most stable media in “regular” lines is Verbatim 8X -R media, MCC02 RG20, if one takes into account user experience and accelerated aging tests. TYG02 doesn’t come close in climatic stability. You can disregard these tests if you like, I’m just passing the info.
As usual, I’ll say that I don’t share this board’s consensus about TYG02 which I find overhyped media, hype based on PIE/PIF scans in end-user drives, which are indeed almost always beautiful looking with TYG02. But professional testing doesn’t show anything specially superior with these discs. Our usual media expert Dakhaas also considers them as being overhyped on this board.
Besides, TYG02’s lower reflectivity is not an allegation. It’s a professionally measured parameter, well, a fact. Which is probably what impacts compatibility with players. I don’t do video duplication anymore, but when I did, I had consistently lower standalone compatibility (i.e. more returns) with TYG02 than with MCC02 RG20. The compatibility kings were RITEK G04 and G05 but as everyone here knows, for other reasons these discs cannot be recommended.
Whatever. Reflectivity is not your concern (and shouldn’t be, since it doesn’t impact usability in the case of data management purposes in PC drives). Your concern is long-term stability. So I advise either MCC004 (Verbatim-branded) or YUDEN000T02 (8X +R) rather than TYG02. Though you didn’t define “long term”…?
But your best defense against data loss is NOT one disc model, whatever its stability. You best defense is putting clones of the data onto different disc models, at least 2. Never rely on a single disc for really important stuff.
