Many thanks for enlightening me - I certainly wasn't expecting anyone involved in CDO to be a poster on this forum!

but as I understand it out of the thousands of discs produced so far there have been almost no returns for reasons of quality.

I don't know why, but this made me laugh. So, just to clarify, there have been some returns for reasons of quality then...  |

"I don't know why, but this made me laugh. So, just to clarify, there have been some returns for reasons of quality then" Sorry I haven't yet figured out the quote box. In regard to returns the rate is less than so called normally produced Cd's which by the way we also retail  sorry no plug meant here The important bit is the music and the fact that it is available again.

Technically speaking, all music CD's are CDR's. What do you consider dodgy? As long as the artist gets their dues...
As to waht you buy, well, it's your money and you choose to buy what you want. Like the 30-minute "Ooh La-La" album I once bought from the Faces.
CDRs and "normal" CDs are different - normal CDs are pressed, whereas a CDO is burnt using a CDR with a layer of dye. |

So, to summarise, CDR's and CDO are the same, so-called traditional CD's are different.
But there's no appreciable differnce in terms of returns / quality / longevity acoording to the manufacturer.
Is that right?
By the way, every CD I buy is immediately backed up in lossless format on my server. This, after long experience of CD's going missing, being eaten by the hippos etc. So I have insurance against their theft by my kids, faults developing, etc. And yes my server is backed up.

The metal layer inside a CD is pressed to create a pattern of indentations/holes that correspond to the ones and noughts of the digital signal. The reading laser is then affected by the pattern of pits in the surface, so reading the digital data stream.
In a CDR the metal layer is replaced by a dye-based layer which is burned by a writing laser. The burning causes pits to appear in the surface that appear to the reading laser to have a similar effect as the metal layer. So CD players can read CDRs in the same way that they read CDs.
The CDR burning process only gives a 'similar' effect to a CD surface though and the tolerances on what constitutes a 1 or a 0 are different. This can mean that some CD players cannot read some CDRs.
Cheers
Nick
