Default DVD burner laser reliability

Don't know about that but I always burn at a lower than maximum speed
because apparently the "image" is burnt deeper and supposed to be less
liable to long term temp/humidity/corrosion corruption of the stored

disc
data.


Agree there, i have tested this on some sample dvdr's and after burning

the
same image
at 1x, 2x, 4x and 8x i could already see the imprint on the disc getting
much lighter.
Let alone burning at higher speeds, often the resulting copy would either
not work or
burning would fail.
Fast cd or dvd burning is a scam, burn always everything at the lowest

speed
possible.
Friends complained about discs degrading too soon, mine still work, same
brand but burned at 1x

Could you enlarge on you could "see the imprint on the disc"
Was that lining up one of each
1x, 2x, 4x and 8x and viewing all in oblique light or viewing under a
microscope?
