One more data point for tonight...
An 80-minute MAM-A gold archive CD just burned at 16x showed 3.8
Avg/sec and 21 Max/second C1 errors.
This is much worse than the silver one burned a few weeks ago in the
same drive, but better than the 32x burn by a bit. The Real time and
32x are gold, the 16x is silver.
Real Time 16x Ag 16x Au 32x
C1 avg/sec 6.5 0.7 3.8 4.7
C1 Max/sec 36.0 18 21 28
There are two possibilities with the gold (Au) disk.
(1) The silver is higher reflectance = fewer errors
(2) The silver is from an older batch (I think several years)
and the coating is thicker than the contemporary
see-through-the-gold MAM-A Archival discs.
While actually none of these is evil, the differences are surprising
on one level and not on others.
