Actually, just to clarify, the program being discussed does not use the clear inner ring of the compact disc, but from what I understand, the program actually burns some kind of information onto the disc itself, or maybe simply creates two visible sections on disc surface, I.E. "burnt" and "unburnt" data, leaving approximately a 1/2 inch section on the inner part of the readable(or reflective) area of the disc, which is where the sample is placed, then the disc IS put into an oven, or anything that maintains a constant level of heat, but not enough to damage the disc itself (hence the 75 degrees), simply to evaporate any water that may be on the disc, doesn't need to be an oven, but there is less chance of contaminating your sample if it is done quickly, and with less exposure to the open air in a room. The main reason for drying the sample is, A: obviously noone wants to ruin a cd drive by putting water in it, even if it is covered, who wants to risk it, right? And, B: I'm not sure if the program can read wet samples or not, or if it just makes it easier to read and analyze, but I am pretty sure the incorporated database only consists of DRY chemicals as of right now, and not just anthrax, but I believe it will identify several hundred chemical compositions, including talc, chalk, or any kind of dry chemical. I don't think they have integrated moist or wet chemicals yet, or if they ever will. Then a protective cover is placed on the disc, such as a D-Skin cover http://www.d-skin.com/, and then placed in the cd-rom drive for analysis.
Hope this might clarify any issues that anyone might not have understood from the original TV broadcast.
P.S. if anyone gets ahold of this software, lemme know, I cant wait to see if it actually works! Just kidding ;P
