I’d noticed a difference in the 12x P-CAV burn strategy between my 755 and 760 series drives some years back. The 755 drives would always do a speed drop in the CAV portion of the burn while the 760 drives would not. It’s easier to show than describe:
I’d just chalked it up to the differences between the two series of burners and didn’t factor in the TLA of the drives, which happen to be 00xx for the 755SAs I have but 01xx for all my 760 drives. I once had a TLA 01xx 755SA but I traded it for a 716SA long ago so I didn’t remember how it burned 12x. However I recently reacquired one this week and I discovered that it burns 12x P-CAV without the small speed drop:
So it would seem the change from TLA 00xx to 01xx, at least for the 755 series, altered the 12x P-CAV strategies to remove the little speed dip. Does anyone have a TLA 00xx 760 series drive to compare?
