Why did it take so long


For digital to finally come of age. It seems that we are finally extracting the full potential of digital. Why did it take over thirty years for them to realize it wasn’t the failure of the cd, but the failure to properly recover all the information off it correctly?

Reducing jitter and improving data reads. What’s the difference? There seems to be a lot of overlap. Besides, scattered background laser light is clearly in the latter camp. So is obtaining absolute level of the disc during play. The Silver Rainbow Foil and the demagnetization we’re not sure. 😛

Those tweaks are only going to have a minimal effect on jitter? That sounds an awful lot like wishful thinking. I would call the effects subtle. Subtle but powerful.

I'm surprised you are asking this.  The difference is obvious. 

Jitter is the variation in the periodic presentation of data bits or data words over time.

Improving data reads means the ability to read data without errors is improved.

There is no overlap.  You can get perfect reads, but deliver high jitter.  You can also deliver low jitter with lots of errors in the data.  They are two different aspects.

Subtle is right.  The only tweak that I found that actually reduced jitter significantly for a CD is to coat the top surface with a thick rubbery compound to reduce vibration.  I used to do this for customers 12 years ago.  You could also buy rubbery rings you could glue-on, but these were not as effective.  I have tried every thing on the list, so I know the relative level of improvement.  They have minimal effect, period.

Even the anti-vibration coating holds no comparison to the jitter you get with a Synchro-Mesh reclocker after the Transport.  Not even remotely close.

Steve, Sorry to hear you haven’t had much luck. I guess that’s the way the cookie crumbles. 🍪 Good luck in your future endeavors.

Nothing to do with luck.  CD tweaks are minimally effective.  Reclockers make a huge difference.  The measurements prove it.

Really? How did you measure the Silver Rainbow Foil? The Green Pen? Demagnetizer? Just curious.
