How many forms of Jitter can you identify?


Just a few days ago I was read about a clock upgrade for a CD player that was said to reduce jitter by having a more accurate clock. Today, I'm reading about a Mikrosmooth CD polishing kit that claims to reduce jitter.

I'm absolutely positive that it isn't possible to apply a product to a CD that will have any effect on the digital clock on the CD player. I'm also skeptical that it can make any difference in how the CD player spins the disk so how does it reduce jitter? At most it should a good cleaning product that could allow the laser to read the disk better eliminating any error correction from being necessary.

What am I missing?

Kirkus well said I agree fully. CD, DVD and Blu-ray and SACD are all made from materials that are non-magnetic.

De-magnetizing appears to be unlikely to do anything.
Only 2 forms I know are Jitterbug and Derek Jitter.

This digital stuff is complicated.
There was or is a tavern called Jitter's in Wisconsin. I believe many had just that the next morning after a night out.
