TIFF and Bitmap are uncompressed files therefore of high quality and do not degrade.
However each file can be as much as 10Mb so you will got only 60 pix approx per disk - assuming it is a 600 Mb disk.
JPegs are about 2/3 Mb per image .
Which is fine as burned they stay as burned however if you import it into a computer and save such a file it saves an already compressed
file by compressing[loosing detail] some more ad naueum per saving.
So there you have it.
