I don't like your chances on this one. The foil is the data surface in that it is the "on" part of the data signal and the media (in the case of pressed CDs particularly). The "off" pits are 1/4 wave-length deep at the frequency of the reading light hence it is essentially a black hole. The optical focus mechanism on the laser assembly is fast but I suspect the lifted foil backing would send it into a spin (so to speak). Anyhow good luck. DVD media is much nicer in this regard as it has two hard polymer surfaces unlike CDs.
