Since no one mentioned the science, the LED light is focused and polarized. By design, it takes care of all this "green sharpie" style nonsense on its own.

>>>>>Huh? Nobody said the CD laser (it’s not an LED) is not focused or polarized. Specifically the laser is a “Quantum well.” The reason the CD laser beam is focused is because it’s coherent light. Polarized light would not be immune to the Green Pen, anyway. It’s the wavelength of the light that’s the issue.

Being funny in the process does not transform dishonesty and contempt into something acceptable. It is just a further form of dishonesty and contempt.

Sorry not buying it.

oh man, vacations over, I can feel another pop quiz coming. 

celander OP890 posts02-11-2019 2:57pmYeah, I worry about using these thingies in a magnetically-clamped top-loader set up. Seems like doom and gloom would arise. This sort of post should cause Geoff to arise and speak about the perils.

>>>You worry too much. NDM is not magnetic. Why would you think it was? Fear of the unknown? Besides, don’t you think a magnetically clamping device is inherently a very bad idea. Hel-loo! NDM is suitable for all CD, DVD, SACD, BLU RAY players with trays or top loaders. I’m not trying to set the world on fire, just start a flame in a few hearts.
