The hole in the CD is where the machine you put it in "grips" the CD so the disk can be spun and thus read and used.
So they don't fall out of the CD player
On the face of the cd player, look for a small hole. With the power off, insert a paperclip in the hole, turning the gears to push the cd out of the player.
most CD drives have a tiny hole near where the CD goes in, just stick something in the hole, like a paperclip or something. Push it into the hole and it will force the CD out. It might not have the hole, I think only computer style CD drives have it.
