I sometimes copy my LPs onto CD, and i have a problem.
It's getting hard to find good quality blank CD-Rs. The quality of a CD-R depends on the dye it's made with: green dyes are the lowest quality, blue dyes are good, and golden-yellow dyes are the highest archival quality. You can tell the colour of a CD by laying a tissue over the surface to block the rainbow reflection. Does anybody know a brand or model of blue CD-Rs? *Special Note* It has been pointed out that i am wrong, that the color of dye used is not an indicator of the quality of your disc.

I don't think it makes a difference. It's just pits. The only thing to worry is if it will detirorate

This site says dyes vary by manufacturer and there's no conclusive proof one is better than the other:
http://www.kopyrite.com/tech_cdr.htm But being organic they won't have the longevity of the regular manufactured ones. |

The latests I have used are Fuji and Sony printable and both look green.
I have quite a few CD-Rs as among my friends we used to exchange original CDs bought by each of us and make copies for eachother, I know we must not encourage copying here but this is the same we always did since the times of cassette tapes, it's micro-scale and nothing to do with nowadays macro-scale pirating.
I really hope all these CD-Rs will not stop playing, many of them are already over 20 years old
![]() Although if it's light what can deteriorate them it should be no problem, I keep them nicely in their cases.

According to the link from Slarti's post, the color of the dye used in CD-Rs is not indicative of the quality of the disc at all. Looks like the premise of my thread is wrong. Edited by presdoug - August 19 2012 at 12:50 |

There was an interesting series on the History Channel called http://www.history.com/shows/life-after-people on one of the episodes they were talking about the decay of various forms of media, books, etc. that occur over time and of course would be accelerated if we were to all vanish from the planet and the various forms of indoor climate control would go offline.
Here's the episode I think: http://www.youtube.com/watch?v=_2xDobH1tb0 The Crypt at Oglethorpe is a few miles away from where I live. It's about 57 minutes into the first episode: Edited by Slartibartfast - August 19 2012 at 17:49 |

yp im also getting annoyed by low quality cd's,and if you listen to prog rock you must have high quality sound.
i always buy my cd's in stores who sell such supplies,like sound speakers,... they are really expensive but they are worth it. Edited by Cloud Forest - August 19 2012 at 16:54 |

I believe Tayo Yuden is a good brand. I've only used DVD's though, but they have been working nicely.

I've always used Verbatim or Maxell CD-Rs. I rarely use anything else.

I'm afraid that after Fukushima we will see increasingly strange colours in all the Japan-made CD-Rs
