TeleDisk is capable of producing either a compressed or noncompressed
image, however, in each case there is a certain amount of 'header' data
prior to the actual image.

AnaDisk, on the other hand, will produce a straight, uncompressed image
without any adds or alteration. You can also select the specific
contiguous set of tracks that you want to save to file.
