iMac SuperDrive problem

in Genius Bar edited January 2014
About 6 months ago I got a new Intel 20" iMac. For the first several months I didn't really use the Superdrive much, though when I did I noticed sometimes it was really loud. It's hard to describe what sort of noise it makes, sort of a really loud buzzing occasionally.. (almost always after first inserting or ejecting a CD/DVD, and occasionally while reading them).

Then later I realized that it couldn't burn CD's. I tried all sorts of different brands, but it always reports a "Medium write error". After searching online I found a tip that maybe lowering the burn speed would help. After lowering it to 4x it burns CD's now with about a 50% success rate.

Frankly, this is unacceptable to me, and I'm finally done with school enough that I can try and deal with it. Do you guys have any ideas? Is this something that the 1 year product warrantee should cover?

In case it helps, here are the drive specs from System Profiler.

Thanks a ton for reading this far and helping me out, I appreciate it.

    If your hardware doesn't do what it is supposed to do, and it is still under warranty, is there any reason you should not try to get it covered? I would call Apple or go to see authorized Apple service.
