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.

That’s very good, stevecham. But why is the sky blue? If our vision falls off after 625 nm how can 650 nm be visible red? 

Pop quiz: what color is a Blu Ray laser?

part 2: what’s the complementary (absorbing) color for the Blu Ray laser scattered light? 
"Pop quiz: what color is a Blu Ray laser?"

It depends on temperature of the environment and an individual’s perception of colors.


What is my prize?

I totally get it. You’re tone deaf AND color blind. But you’re probably lucky in love. 🥰

Color is your perception, not the absolute value. You also forgot that I may have problems with temperature sensitivity.


I am still waiting to find out what my prize for answering pop quiz correctly is.

Did I say that your adhesive plastic thingies were magnetic? Seriously? (smh)

My fear is having my CD’s torn up by contacting cheap adhesive plastic pieces in a top loader platform due to a magnetic clamp being on top of the CD. Fear of the unknown is not a fear. Fear of the realistically possible is however.
