Apparently blu-rays are even worse than other discs. This is from the abstract of an accelerated ageing study (sadly I don’t have access to the whole paper):
Overall, the stability of the Blu-ray formats was poor with many discs significantly degraded after only 21 days of accelerated ageing. In addition to large increases in error rates, many discs showed easily identifiable visible degradation in several different forms. In a comparison with other optical disc formats examined previously, Blu-ray stability ranked very low.
