Of course, you are completely wrong as other posters have pointed out -- CD is indeed a fully digital format (but it does not have a filesystem, just a continous stream of binary data with a TOC section near the beginning of the disc to tell the CD player about the timecode location of the tracks) I thought it would be worth mentioning that you may be confusing CD with Laserdisc, the video format. Those look a lot like huge CD's but are in fact analog and work more like what you describe.
