Disk drive not working

While trying to get some music off of old CD's I experienced a problem with the CD/Disk (whats the correct term?) drive on my Mac Book Pro. It would make light humming noises for a few seconds, click, some more humming noises, and then spit the disk back out. Unfortunately my computer was around some young children a while ago and I think they may have shoved some paper or something into it. Are there any suggestions as to what else may be the problem and what I should do?

Also, would the Apple Hardware Test tell if there is something wrong, I have tried it and it would boot right into OSX. (sorry wrong section, didn't want to write 2 posts)

Thanks for any help I get!

Specs:
MBP 15" 2009

Disk Drive: MATSHITA DVD-R UJ-868
Running Snow Leopard

It's difficult to say what might be wrong with the optical drive in your MBP. If there were paper or some other object in the drive it's likely that you would not have been able to insert the CD. The drive might just be defective. The slot loading drives in Macs seem to fail much faster than tray loaders do.

You can try cleaning the drive with a can of compressed air. Blow a couple of short blasts into the drive. Cleaning disks are usually not effective.

The Apple Hardware Test won't diagnose a failing drive. It's best to replace the drive yourself if you feel up to doing it, as that will save you labor costs. You can get an idea of the procedure at iFixit: The free repair manual.

Thanks for the response, I guess I'll try the canned air thing and if not I'll try and fix it.

Thank you soo much! The canned air worked perfectly! You don't know how happy i am!

OK, great. Glad it worked.
