I think I’ve learned my lesson…I was using labels until I discovered the printable ones. Here’s a perfect example of what a label can do to a DVD.
First Scan - with label
Second scan - without label
As far as the second scan goes, this DVD was a duplicate so I did not clean it properly…I used a solution by the name of Awesome Orange which can probably clean grease caked on someone’s engine, (it even smells like engine cleaner) I used paper towels and a kitchen washcloth to wipe it dry. The spikes towards the end are more than likely due to the scratches on it since the disk was on a not so clean surface when I was taking the label off. The label has been on this disk since August of 2007.
Think the results are conclusive?
By the way, anyone have any idea what kind of disks these are? I bought and used these up long before I even knew about thsi thread and they have given me some decent scan results.
