RE: CD-R Burn Quality and Laser Noise During Playback

I settled on the Verbatim/Mitsubishi "AZO" and "SuperAZO" discs as the best for audio. These are the ones with the (originally) very deep blue, but as the layers have become thinner (as the rated speeds got higher to 52x) these are more Baby Blue compared to the more ubiquitous pthalocyanine organic dye (the ones that look very pale cyan/goldish). They also have a longer life expectancy. I would say that if you are having issues, it could be because the organic dye layer has "aged" beyond its useful life. These days, who knows how long the discs have been stored since manufacture when you buy them as "new"?

The pthalocyanine discs became the most common because the early AZO discs had issues with achieving comparable high write speeds which everyone was demanding in order to save time. However, they also have the poorest longevity (even when unused).

That said, I always write at the minimum speed possible for the drive in use and have never had any problems with either type skipping in CD Players or error correction issues unless the laser in the target player/ CD Rom drive was already getting weak or the disc was damaged or had aged in storage - I used to buy them in bulk and I had some "cheapie" brands where after 5 years storage, the discs became unusable. AZO discs have a better life expectancy. However, even my original Philips CD471 had no problems with any CD-Rs. It wouldn't touch CD-RW of course, but surprisingly my Sony XA-30ES would until the laser started fading.

The software I used (going right back to 2000 when CD blanks were still expensive) was mainly Feurio and then Nero. The CD Mastering software bundled with SoundForge Pro also has never given me problems. My drives originally were one of the first HP writers, then a Pioneer DVD writer, a BenQ 1640, LG and Samsung BD writers. The software actually should make any difference to the actual burn quality - that is all taken care of in the drive firmware.
