CD Compartment Trouple

Having some trouble here. Its with an apple mac though. Every time I put a CD in the Compartment, it doesn't grab it until its almost completely in the slot.

And when it pushes it out, only the very Tip of the CD is shown, and I need to grab it and pull it out as the computer sucks it back it. >.> I know that's stupid. It can't be good for the Computer, and its possible the CD could get damaged in the process, but how else am I suppose to get it out?

Anyway, I wanted to know is their anything I can do about this? Is the computer just busted? Is it a setting that can be fixed?
