Here's how a CD is made

THANKS for posting the heads-up Ccc. Fascinating article. It's quite a miraculous technology to a simple man like myself.

I was particularly intrigued by this passage and accompanying footnote and would be interested if anyone else had observed similar results:

"Another example of how two discs with identical data sound different is the strange case of copying (in the digital domain) a CD to a CD-R (a CD made on a CD recorder); the CD-R sounds better than the disc from which it was made. Although the data are identical, the CD-R's HF signal looks much better than that of the mass-manufactured CD (footnote 5).

Footnote 5: At the 1992 Winter CES, Meridian's Bob Stuart copied a CD to a CD-R of music that engineer and high-end retailer Peter McGrath had recorded. Bob played the original CD, then the CD-R. Seconds into the CD-R, Peter jumped from his chair and exclaimed, "That's impossible!"

Excellent find Cdc and thanks for providing a link to this article. Very informative and easy to understand / follow along with. Truly one of Robert Harley's better works. Sean

Thanks for the link, it was a very interesting article. I was especially intrigued by the CD-testing machine described at the end - I wonder what such a device could reveal about the quality of CD-R blanks from different manufacturers.

Thanks Cdc, This was the best and most easy to understand read on Cd's I've ever come across.

Very interesting. So much for perfect. The forever part will take a little longer to evaluate.
