Cleaning them is not such a bad idea, after all there's still a laser shining on the disc surface, and any stray light caused by a film of dirt will affect the HF signal. Most stuff is perfectly technically explainable.
Funny how the CD has a digital character, but a lot of technique behind it is just analog

Does anyone know where I can buy original vam lasers from on-line. Every time I think iv'e found one I end up with a non-working chinese copy. My cupboard's full of them. There used to be a time when they came in a philips fawn box and with wires. I now find the same is happening with the Sony lasers too. I'm not trying to get them cheap, just real!

If you have a cupboard full of old lasers, check out the threads on repairing them - worth a try.

Seems a lot of working drives have been thrown away when all they require is cleaning on the underside of the lens.
You've got to have good eyesight and a steady hand though !

often on those chineese lasers, all thats needed is the spindle needs lifting slightly.
Worth a try if you have several. I've had a few that just dont work, but I've neve had one that didn't after adjusting the cd mount on the end of the spindle. They've normally be squashed at some point an a small screw driver to lever then up a fraction is enough. Make sure you apply pressure evenly all the way round!!!
