using your cd-rom to test for anthrax

Ok, so I don't know EXACTLY how a cd laser actually reads the cd, but my little understand is that it reads binary code? So there is a series of 1's and 0's on the disc that compiles the information.If the cd drive is reading reflected light back through an optical sensor in a form of resistance. Is it possible that the resistance can be variable, and not limited to just 1's and 0's? Then the reflected light through the anthrax can help determine it's thickness. You should be able to get a repeatable result.Or if it is limited to just 1's and 0's, or light/no light, is it possible that the width of the anthrax residue is much greater than the resolution of the ability to read the refracted light?I am not even sure what anthrax is. Isn't it some kind of organism? What is the width of one? Is it greater than the resolution of the laser?Once you add it to water and cook it (BTW, I think it was 75 degrees, but Celsius, not Fahrenheit) does it crystallize, and leave a consistent pattern that the laser could easily read?Also they said cd, or DVD, so my guess is that they are using a DVD drive, which can read finer resolutions.Well anyway, to me it all seems possible.

I never said the clear inner ring.
That was something that jar assumed I meant. He assumes that I know nothing about how a cd-rom works.I assumed that everyone here does know how a cd-rom works, so when I mentioned the first indside inch, I assumed that everyone would know that it was the first inch of the cd that is readable.How is a cd reader going to read where the laser can't reach?Just stupidity if you ask me.People in here are only smart when they want to be.If it was someone like rrhain or scraf who would have made that comment, everyone would have assumed it was the first readable inch, not the clear inner circle. That is why I never addressed jar comments. They were directed towards a 2 year old. I noticed that in the program, but I do think they said blank cd. But you know these programs don't always get the story right. Or if it was right, it wasn't taught clearly enough. The 75 degrees, must have been celsius, since I found the model of the oven they use, or one that looks exactly like it, and the temp starts at 50 celsius. I don't think they mentioned farenhiet or celsius, and I just assumed, it was a controlled dry temp that was needed to just dry the drop of water. I figured it was the humidity that was more important in drying the water. Given the rpm's of a cd-rom, I don't think the wet sample will stay on.Also that is another reason they use the inside of the cd, and not the outside, the actual speed inside is less, so the crystals won't fly off. Plus the program probably uses the variable speed of the cd rom to keep it slow. When I watched the show, they said there was 150 samples so far.
