Larry Miller, former Ampex electrical engineer/designer and one who has sat on several networking

and the robustness of error correction protocols. I believe it is unrealistic to expect too low
an error rate in burned dye media, but the error-correction has proven very robust over time. Not
to say a trashed disc is not a trashed disc, but to say we should not make too much of tiny
errors that are easily corrected and accepted in the protocols just because we can detect them.

I have little disagreement with what you offer, but do note that there appears to be strong
correlation between substantial initial error rate and rapid degradation. I have guesses on the
causes, but insufficient data to go further than to establish the rules for myself. In a similar
vein, low initial error rates seem to correlate positively with easy readability. Again, one can
speculate on the causes, but it may be enough simply to use reasonably minimized errors as a
selection criterion for media - along with cost, availability and other factors.
At the least, I recommend to all that burning be limited to speeds near that which gives the
fewest errors.
