Up loading Music CDs

I have a problem with my Macbook in that when I am loading music CD's into itunes 50% of the time no CD is recognised!!
I never have this problem when I am loading software and cannot see an obvious difference between the CDs.
I thought it was a hardware problem but I am not too sure given that some work and software is not a problem. Any ideas??

Check the discs to see that they are clean and scratch-free before you try to load them into iTunes.

Especially the top! Discs are still potentially readable with scratches on the bottom, but if there is damage to the top, you're screwed.

The discs are new and therefore should be ok!
