Get a bunch of cotton swabs. Now with each cotton swab wet it a little so that the cotton part gets thinner and longer. Then when the cotton part of the swab is dampened(not soaked), very, very, carefully slide the cotton part of the swab back and forth in the tight disk thing. I tried this on mine because somehow a ton of dust made its way into the disk drive. What the damp cotton should do is pick up all the dust(if that is the problem). Try just one cotton swab and see how that works.Be careful though!
