Copy CD's to CD-R

After reading this great resource on music and hearing too many innovative tones and lyrics, I feel it's true, Music is like nutrition for soul. And any one who tries or preserve it is doing great job.

At that time as now, the finished, recorded pit structure of a CD-R offers superior transitions from land to pit (bump) than on most any pressed CDs (JVC XRCD excluded). Simply put, this produces an optical eye pattern to the laser reading mechanism of a CD player which creates much more accurate square wave patterns that are the analog representation of the digital signal.

It is here where jitter normally sneaks in, because the optical eye pattern must be interpreted by an optical sensor, whose accuracy is directly effected by the clarity of the eye pattern.

Small deviations in timing (jitter) are not recorded nor correted in our single ended 16-bit PCM recording system, and this has been a problem all the way back to 1980, when Phillips and Sony took a few short cuts.

The result is that the same data from a pressed CD will always sound more transparent when dubbed to a CD-R. It is simply a matter a physics, and lack of recording the time signal from the original A/D!

As you know I am new to this Forum, and reading this particular item gives me great satisfaction to know that 3-4 years ago I burnt some CDs on CD-R and did feel they sounded "cleaner" to my ears. Now you have confirmed it. Jut one problem I had/have with these copies is that after playing for sometime on my car CD player, they begin to mistrack/stop or go funny. So i just stop and next day it seems ok. Wonder what the reason is?

The dyes that are used for the data layer of a CD-R can become unstable if left in a hot car for any length of time. So perhaps the disc is heating up - creating data errors and mistracking, but this change is only temporary - returning to normal after temperatures return to normal.

Does that coincide with your experiences?

Yes. That is what happens when it gets hot.I know now -thank you.

I think CDs sound better than CDRs
