Say you have a quite rough quality scan all the way thru your disc.
I could happily accept that it's probably due to the quality of the blank itself, the dye etc etc etc.
But often you do a scan and it's all superb, really low, then out of the blue, just one blip out of nowhere, then back to low for the rest of the scan.
Obviously the media (in general) is good, so where did the 1 blip come from?
Would is more lightly be a spec of dust/dirt on the surface, or does than not cause things like this to happen, and it's more lightly to be a tiny flaw in the disc itself?
Just wondering as it's annoying sometimes, you think it's looking great then all of a sudden, "Ping" one tall error line.
