CD's are the opposite of records and start on the inside and move out.

The data is on the bottom (shiny) side.

Try some eyeglass cleaner and a cloth. If that doesn't work, you can buy a disc doctor and that will cut a thin layer of plastic off the bottom and hopefully fix the problem--but I would recommend taking it to a DVD rental place or a used video game store. They will usually have far higher quality machines.
