[QUOTE="gbyleveldt, post: 69947, member: 122"] Actually, it can be the lens. The way an optical system determines if there's a disk in or not, is to actually hit the disk surface with high levels of laser energy the moment the tray closes. It tries to detect the reflective surface of the disk by focusing the lens repeatedly. It tries this usually 3 times, if nothing reflects back, then it gives up and says "No Disk". Now, there's a million reasons why the detector does not pick up the laser beam, one of which is a dirty lens. Others reasons may include things like tired lasers and faulty focus drive (either lens or electronics). [/QUOTE]
