Ah yes, a subject near and dear to my heart:
Moser Baer India once made coloured substrate media for the Imation Neon range. Unfortunately no more
As did Moulages et Plastiques de l’Ouest (MPO) who made CD-Rs in blue, red, pink, orange, green and black but again, they seem to have stopped: however if you are interested in a bulk run of Audio CDs/CD-ROMs (i.e. 3000+) you can get them in whatever colour substrate you like.
A residual stockpile of coloured CD-Rs from MPO is here:
As a very long time user of CDs with black/coloured substrates I can tell you that they work perfectly, similar to normal translucent substrate discs. Except of course, if they’re made by CMC MAG in which case their dependability cannot be guaranteed over the long term.
They look great and I would very much recommend those Databank printable top black bottom thingies http://www.blankdvdsupermarket.com.au/proddetail.php?prod=100B1550.5
for any use where style is more important than longevity, however I would add one word of caution.
One time, I had an Optiarc 7191S drive (total heap of :Z btw) that in addition to routinely screwing up lightscribe labels, also could not read or write CDs with black substrates, of which I have a lot of from the likes of Prodisc CMC MAG and MPO. Ditto for the green and blue MPOs which are very dark.
Needless to say I promptly RMA’ed the POS, though because I don’t know whether it was a unit fault or a design flaw with that manufacturers products, I would recommend that you test all your equipment with these discs before committing to any serious use of them. Also to avoid using them in any case where you have no idea where they will be used, such as promotional or demonstration discs.
Does anyone have a current Liteon/719x Optiarc drive and can add to this?
