Problem with iMac optical drive

My iMac keeps spitting out discs. It will take some and then it will spits others out. I've tried just about everything. Anyone have any solutions? I was able to install Printshop and it took that disc. I burned some audio cd's and dvd's and it won't read them, just spits them out.

First; You posted in the wrong forum, please read the descriptions of the forums..
Second; Please use descriptive titles..
Third; Post the specs on your Mac. How old. What version of OS X and so on. How long has it been doing this?

My IMac is a little over a year old. It just started spitting discs out about 2 weeks ago....
Sorry, didn't mean to post in wrong forum. New to mac forums...

What does this have to do with community suggestions? Read our forum descriptions before posting. Also your title was edited for clarity.

I had the same exact problem over the span of four months; I tried everything. Finally, I just took it into my local Authorized Apple repair store to replace in the optical drive and never has given me problems since.
