Nah, my personal experience told me it's highly unlikely that long. Last time I checked my CD/DVD archives of around 10 years old. Checked some random 20% of all, 50% were completely unreadable, 30% readable but with noticeable losses, other seemed to be good but still I had no confidence of the integrity of the data. So I dumped all of them, even almost of full bucket of 50 unused DVD-Rs and quite a few DVD-RWs. Since then I did not really touched any optical drives at all. To my surprise, all my data left on HDDs or Flash drives were still good without any issues.
