You could consider using a suction cup with a Lego pneumatics system providing
the vacuum.
(I vaguely recall a project that made a Lego robot that could climb
a sheer pane of glass using this kind of technique. I know Rob Stehlik built it - but
every web site I've found that talks about it refers me to a non-existant web page.
Well - someone here will know how it was done.)
That way, you'd only have to lower your arm down on top of the stack until a
touch sensor triggers - then turn on the suction - move it over the CD tray and
release the suction. Reverse the operation to deposit the finished CD into
the output hopper.
This would be a good approach since it would completely avoid the risk of scratching
the side of the CD with the data on it.
