I can't vouch personally, but I have heard reports that verified media properly stored (in a light-proof case, in reasonable temperature) going bad after few years and maybe even shorter periods. It may depend on the recording drive and particular media manufacturer, but I haven't seen a definitive long-term data retention study. This isn't helped by the fact that well-known brands (Maxell, Verbatim, HP) don't make their own media but rebrand OEM product, sometimes switching supplies, sometimes with diametrally different quality. TAIYO YUDEN is often mentioned as a prime manufacturer; a reasonable writeup is on http://www.best-dvd-burning-software-reviews.com/best-blank-dvd-media.asp
