Yep! - another failed project.
CDs don't work like that, the audio isn't impresed into the disk like it is in vinyl, the sound is first sampled at a high rate, in the case of CDs it's normally 44100 times per second, then the samples are turned into digits, then a compression algorithm is used to optimize the signal to noise ratio and finally the bits in the data are saved to the disk as long or short length pits. The disc writable layer is not capable of direct analog recording.
What *might* work is an optical pickup on vinyl records but special care would be needed because on a normal record deck, the stylus tip is responsible for moving the whole arm assembly. An optical system would need servo motors to maintain tracking.
