I think that is how most slot load CD drives (i.e. computer drives) work. Auto stereo CD players seem to work a bit differently. unfortunately the video doesn't really get into it all that well, but from looking at a few of them, it seems like most have some kind of sensor (I think most are optical) that sense when a CD is inserted. They then use pinch rollers to grab the CD and pull it in.
