Photoshop :: Image Adjustments At The Center Of A Circle

I just got a new Lightscribe drive and I have been having a field day making custom labels for old data discs. Now I have decided I want to make some backups of some of my games so I can put the original discs/boxes into storage finally.

The problem with this is that Lightscribe discs have a larger "unprintable" radius at the center of the disc that other media. I found that when I scanned some of my discs and imported them directly into the LS Print program I was losing alot of information/text/pictures.

Essentially I need to take a point in the center of the circle and 'stretch' it outward in a circular pattern. (If you have seen Ace Venctura 2, think about when he had to escape from his mechanical rhino-spy vehicle through its bum I have also attached an image so you can see exactly what I mean. The read circle in the middle is approximately where the most inner edge of a LS disc can begin to print.

where to even begin as far as keywords go. I do realize that there will be a certain degree of 'smushage' (technical term) on my final product, but I would rather keep the original disc look than having to make my own custom disc for each game.
