A poor quality microscope is possible. If you found a way to hold down the specimen at 300-3000RPM AND if you wrote a firmware routine for the DVD drive. Only programmers that can program in machine language can do this. Possibly you could read the specimen without the firmware but it would be ONLY a 1 bit image(on or off). Image quality wouldn't be very good. If someone would replace the photodiode sensor with a A to D converter you might be able to get a descent quality image but that means modifying the CD or DVD drive.
