Hmmmm....April 1 was on Monday. Did somebody get a belated memo?
Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?
This is a set of adhesive-backed thin plastic pieces that one attaches to one’s transport or player disc tray. The disk rests on them during non-spin mode, but presumably don’t touch the applied thin pieces during playback mode. The company says the new Dark Matter pieces reduces background scattered light from reaching the photodetector, thereby improving performance.
Anyone tried this product? Please specify transport or player if you have and your impressions.

The sensor detects the light at the same time whether scattered, reflected or direct. >>>>You’re no fun, Moops. You just answered your own question. |
moopman b) Also black matter being black only means it absorbs the light we can see, just like other black things. That alone provides no evidence that either IR or UV wavelengths are absorbed. Even if it was proven to absorb IR, and other black things not, it would not seem to matter given point a). >>>>You said it was black, not me. |
moopman BTW, anyone know the actual EM frequency range that sensors used in CD players actually detect? That would be a good start to know what will be most effective in absorbing the light, not that it is likely to matter... >>>>Yes. I do. Now, see if you can guess what frequency range the CD laser operates at. |
