| The copy should be absolutely the same as the original.
The proof:
1. Read your original disc, create an image.
2. Write the image, create a copy.
3. Read the copy again, make another image.
Compare these images with fc /b under (4)DOS prompt.
No differences should be encountered.
If you can call THAT quality loss, then I don't no that quality loss should be.
The condition is that you have corrected BOTH offsets on reading AND writing (as far as possible technically). |
