Disk driver problem

Hello,well im having a problem with my acer aspire s315 and the problem is that a few days ago my disk drive stopped reading my disks at all. i dont know why it is but now when i put in a cd like one of my music disks they wont play at all. im getting mad at whats happening because i bought a game and its a key game and the driver wont play it anymore. will some people tell me whats wrong??
