My cd rom drive will not recognize any cds...

My cd rom drive will not recognize any cds or dvds. When I put a disc into the drive it will tell me to insert a blank disc into the drive. I have tried over ten different discs (including the one that came with my computer) and none of them worked. I have tried cleaning it with canned air, a plain paper towel, and a plain Q tip. Nothing has worked. I also bought a lense cleaning disc, but my cd rom won't even recognize that either. I also tried uninstalling/reinstalling my cd rom drive, but that did nothing either.

Here is some important information about my laptop and cd rom drive.....
* I have a Gateway laptop. The model is M-6823 a.

*I have an Optiarc DVD RW CD rom drive, and it is an AD-7563A ATA Device (I think that's the model number for the cd rom drive.)
Thanks for everyones' help:)
