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.
