Cant play games? Wierd problem

right so I just got a used copy of Halo 3, and though it was slightly damaged, I figured it would still work. However, I am getting a strange problem. Whenever I put a disc in (not just Halo 3, but any game disc) it says reading for a few moments, and then goes to "Open Tray" It's as though my 360 wont register the disc in the tray! It's really bugging me because I am dieing to play some of my 360 games lol. Anyone know how to fix this?

Sorry about your problem mate ,But sureley it should come as no surprise that your Xbox is having problems,Disc drive failure is another commom fault with 360's but clean tour discs and lens anyway ,good luck
