How Does a Car CD Player Work?
 

I suppose this is a technical question. Does anyone have good information, or a good website or video, on how a car CD player works? I am not so much talking about the laser reading the CD, rather how the unit pulls the CD into the slot. Is is a photo sensor that knows when a CD is inserted? Does it use rollers, or an arm like front load CD players do?

Here's a video:

That's a useful video, thanks TWA884.

As far as I remember, there are two arms inside a slot loading disc drive, that pivot around a pin. Inserting the disc causes one arm to activate a switch, which causes a motor to drive the other arm which in turn moves the disc onto the spindle. Ejecting the disc does this all in reverse...

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.

Okay, I stand corrected! I was assuming car CD players work the same way as slot-loading CD drives. Thanks for your reply.
