Bake in an oven at 75o F? Right. Go look at the temp dial on your oven. Why not just leave it on a counter top for 20 minutes. Most homes are 70o or so.

It seems that the CD isn't blank but has some sort of pattern of data on it and different substances would scatter the light differently, so there might be some way of identifying what was on the disk. The thing is, if it were anthrax, the last thing you would want to do is handle it, much less spin it around at very high speeds. It would be slung all over the place if the cd wasn't sealed properly. It seems to be still in the research phase at any rate and may use special equipment not just any old cd drive as the article does refer to "new CD sensor technology".
