End of life DVD-RW[edit]

What would be the mechanism of failure whereby a DVD-RW or similar, fails after around 1000 write cycles? Would it fail to cystalise, fail to melt, or deteriorate in terms of optical characteristics? Anyone know? Colin99 21:19, 2 January 2007 (UTC)

I came here to ask the same question. Why is it 1000 cycles? Tempshill (talk) 03:20, 3 June 2008 (UTC)
I think it is due to material degradation, ie some phase separation (change of chemical composition), contamination by other layer during melting, ... and also probably due to mechanical degradation - due to deformation during writing/erasing processes. — Preceding unsigned comment added by (talk) 12:06, 31 May 2011 (UTC)
