"Reliability" usually refers to probability of failure over time. Since 
the time spans involved in CD-R degradation are of the order of decades, 
there's little hope of getting meaningful results during the lifetime of 
the product line. Accelerated life test is wonderful - if there are 
reasons for believing that the relationship between acceleration and 
'reality' can be established. I have seen no science, recent or 
otherwise, that suggests that altering a parameter by X is equivalent to 
multiplying test time by Y.

I am reminded of a boss I once had who suggested accelerating software 
life test by running the computer in an oven.
