PSP UMD bzzzzezzzererrrzzz help!

[Dazzerr--]

Hello,

After reassembling my psp i have encountered a problem regarding the psps UMD.
I insert the UMD as usuall and then the psp reads it (like it normally does) but when the laser moves left or right it makes an anoying  bzzzzezzzererrrzzz kinda noise (if yer know what i mean). I smell nothing wrong but i can see the problem. The laser is sliding along the UMD disk (its touching the umd disk). Everything works fine exept it makes that enoying noise. It makes alot of sound!

Does anyone know how i can fix this?

Would be most appreciated, thanks in advanced...

Use a dremal and take off a bit of plastic where the gears are. The gears are touching the plastic right now.
