Theoretical question about how CD's work

Here are a few other audiophile thingamabobs that improve the sound of CDs that ought to get the 1s and 0s crowd’s blood boiling 🥵.

Nespa High intensity strobe light CD treatment

The Intelligent Chip quantum Chip for treating CDs, and the Intelligent Box (Think Inside the Box)

Audio Deske CD Improver - edge beveler for making CDs perfectly round

The PWB Violet Pen for coloring the outer edge of the CD. Interestingly, the Violet Pen also works on LPs.

Folks, I don’t think anything more needs to be said after Geoff’s last post. How can you possibly top that list of ridiculous snake oil solutions to problems nobody has ever had?

And who cares how round the edge of the CD is? That doesn’t fix track concentricity issues. CD don’t spin on their outer edge. They spin from that hole in the middle. DUH. R

>>>>>The reason out of round CDs are bad for the sound is because they wobble and flutter during play due to their mass not being uniformly distributed. Thus, the laser servo mechanism is overloaded trying to keep the laser on the nanoscale track.

That is why a few CD manufacturers have created clamping/isolation devices for the CD wherein the vibrations from an out of round CD are greatly or completely diminished.  Even my EAR Acute has a flimsy CD tray and internal puck to hold it while it spins.  This is a basically a design error by most manufacturers in eliminating non-concentric and floppy discs.  Same with DVDs, Blu-Rays.
