^the trick is to put a tissue paper on a disc when  it is not playing, there is usually a multi coloured kind of rainbow effect of colors, and when you put a tissue over that rainbow effect, a single color will manifest itself (obviously you can't do this while it's playing) the pretty colors you see is a common rainbow color effect that does not indicate quality at all

At any rate, it has been pointed out on this thread that the color you see when you use a tissue paper over the rainbow effect, showing  the color of the dye used, is not an indicator of the quality of the disc at all.

What do the one colours indicate then? I thought it might be the way it is coded for copying

That is a good question, ACR, I'm not really sure.I'll have to read through Slarti's link again, maybe that article will explain that

I just noticed that you qualified your tissue suggestion with "when it is not playing." Sleepy

The image of someone trying to lay a tissue on a rapidly spinning CD-R to ascertain its color strikes me as very funny indeed.

^^that does sound like something pretty self evident! I didn't need to point that out, really!LOL
        I guess i meant to say that you cannot notice the dye color by watching your disc as it is playing

The question may really be why archive to CDs at all ?

I have nearly given up using mechanical forms of music playback and recording since sooner or later a CD's drive mechanics will fail, alot sooner than a well made Hard drive , SSD or SD card.

I was on the bandwagon of recording certain Lps to disk or making compilation CDs for trips etc. But when the media would not play well or at all in some rental car players and in portable units which were just never made to be 100% shock resistant, I gave up on it all.
I was using Verbatim for CD and DVD and still have a few hundred left which I will keep .
That brand has been pretty consistent with their burn results.

When deciding what brand to go with I reviewed many on NewEgg where a wealth of info regarding discs and manufacturers was revealed i.e different disc plants, processes etc.

The future of better quality is in your PC or Mac. CD's are dead.

That's not true, but i don't want to get into this debate.

About CD Rs, not (not the audiophile burner ones), there are the "Mitsui"
which are reliable.

That is a good question, ACR, I'm not really sure.I'll have to read through Slarti's link again, maybe that article will explain that
The rainbow effect of colours is merely a prismatic effect of the pits in the dye reflecting light off the alluminium layer which is then defracted by the acrylic layer. The base colour of the dye more or less determines how long it will retain data - however, telling one dye from another is not quite that simple as a blue dye over a gold reflective layer will look green obviously. But what really determines the quality of the CDR is how well it is made, not what it is made of, and there is no real way of telling that just by looking.
 
Contrary to urban myth or popular belief, (whichever is the greater), the quality of CDR does not affect the audio quality of whatever is recorded on them - what the quality of the CDR determines is how fast you can write it and how long the data will last.
What?

I remember when being able to record a cd was a new and wondrous thing. Around that time these were introduced and they promised they would be good for a lifetime of storage. http://www.amazon.com/Verbatim-Digital-Vinyl-Multicolor-Spindle/dp/B00009WO51  Not sure about actual longevity though.

I would not use anything other than MAM-A CDs (Google it). They are gold plated archival CDs. In theory they should last 99 years before deteriorating if kept in proper temperatures and such. They will outlast any other digital media including computers and hard drives for sure. They're expensive. If I recall, a package of 100 was about $200. I'm an amateur guitarist. Professionally, I'm a linguist working who works on an endangered language, and good long lasting archivability is a very serious issue.

Taiyo Yuden CDs/DVDs are often called the best you can buy. They are one of the co-creators of CD-R.

Do a little research on the manufacturers of all those blank cd-r +their companies mentioned in this post.
You may be surprised at the findings.

Well I did a little research myself and DEAN, once again you are absolutely right. I can always count on you.

I gave up on cheap CD-R's many years ago. If I am burning something for a friend I will use Sony CD-R Digital Music. If it's going into my collection from an album or obscure download...I go with a blank MFSL Gold CD-R, they are like $2.99 at any Guitar Center in the USA and I buy them a dozen at a time. You can also get Delkin 25 pack spindles for around $50 bucks. That may sound expensive to some, but I can't stand sunspot jumps or bad recordings in my collection.
