by anil2 / December 31, 2004 4:10 PM PST

My past experience tells me that with time Lens in CD ROMS or DVD/Music Systems fails to read certain CD's while they may read some Music CD's,but will fail to read DVD-R/CD-R or Mp3. When they are brand new they work excellent.somebody told me that after some time lens are to be balanced like our Rims and Tires.
Please can somebody guide me how do a CD lens work what's the life of CD Lens and how to clean or repair them?

"CD-ROM Laser Lens Cleaner"

Before doing anything drastic - try running a "CD-ROM Laser Lens Cleaner" in the drives. If that doesn't improve things - try something drastic!

Sometimes you get lucky

I have been able to get a few working again by dismantling and cleaning the plastic lens. I happen to have some special swabs and alcohol used in critical cleaning of laser pathways used on medical devices and such. This is followed by a good interior dusting with compressed air. I'd have to say my success rate is no better than 50% on those where no detectable mechanical failure has occurred. If I can't get it to work, I toss the drive but keep the belt.
