The same thing happened with mine last year. I ended up sending it in, but it was still under warranty so it was free. Now it's happening again, but I found that if I just open and close the disc drive a bunch of times it eventually reads the disc. People online also suggested tapping on the top of the Xbox while it's trying to read the disc. I would just try opening and closing the tray a bunch of times and if that doesn't work either send it in or try a DIY replacement of the drive.
put the disk in and start up the game. then try blowing in the xbox where the vents are, or spray air duster in it (be careful not to spray to much in usually just a couple quick sprays). If that doesn't work flip over the xbox while its trying to play the disk it press on it while its upside down, sometimes the thing that reads the disk gets loose and you have to push it back into place. i worked for me, hope it works for you best of luck man!
gonna have to sy this just cause but maybe you should invest in a PS3 they have less problems. if you can try to get the older style if you do wanna go that rout for seriouse. On a serious note yah check ebay you can get some good deals on part replacements. I've fixed a wii and 3 iPods from ebay. gotta love being able to replace parts yourself.
But anyways thats a bit off topic, i'd rather go home and eat some fancy dish soaps.

Okay, some of you might think I'm joking, but I'm not.
After you put the disk in the tray and the tray is closing, when it's trying to read the disk, just bang the top of you xbox kinda hard. (Not enough to break it obviously,but a pretty good hit). This should move the laser or disk just enough for it to read the disk.
Also, if you get the disk to read once, download it to your hard drive right away. This will make sure that even if it can just read a tiny bit of the disk next time, you will still be able to play it.
Happened to me a while ago.

Haha yeah the banging thing does work. I tried it. I just go with the open/close repeatedly method these days, but recently I have been having no problems with my Xbox, which is weird considering sometimes it won't read a disc for like a week.
