Does coloring the edges of CD's help the sonics?

Shadorne, everyone thinks the AudioDesk trues the radius of the cd. It doesn't. It puts a angle on the edge that extends only half-way through its thickness. It thus is really just directing the light diffused through the plastic downward. You could trim both sides. That would true the radius. I did that with several discs with some benefit, but you need to be very careful not to scratch the disc and it takes too much time for the additional benefit.

With improved cleaners, as for the painting of the outer edge, I found little benefit, which again suggests that it is not disc wobble.

That would make it harder to explain. The reflections then would need to be enough for the CD player to resort to interpolating some unread data. ( which does occur on badly damaged/scratched CD's but should not be the normal way of things )

For more info to see how CD players do a lot of checking on what they read see this. It is kind of like the game Mastermind board game or Cluedo - after a while you have enough redundant data to be sure what you have hidden from view (or in teh case of a CD what data was misread). For sure audio CD's do not have as much redundant data for cross checking accuracy as a CD-ROM disc(where a single error could mean that software will not run on the computer) - but it should be more than enough to weed out errors from misread bits due to odd scattered reflections of light...

Shadorne, the new cleaners also make scratched discs more readable or at least less likely to cause the cd player to err or pop. I think the laser's rays merely reflect on the sensor with little diffraction elsewhere.

I still remember the demonstration with the red leds. The player just stopped.

Something has removed the modest benefits of painting the edges on discs, perhaps I err in attributing it to more transparent discs.

The blade on the disc trimmer should be positioned such that the entire edge of the disc is timmed at an angle, not just half the edge. What good would it do to trim half the edge, as the light would still be directed out the half that wasn't beveled? The other advantage of beveling the entire edge is that it makes the disc symmetrical, cutting back on wobbling during play.

Geoffkait, it has been a long time since I got the AudioDesk, but I think I aligned the blade as recommended, which was half way through.
