95397	2002-11-02 04:25:00	Is there any diffrence between (a) CD-R s used for data backup purposes and (b) those marked 'CD-R Audio' for creating music cd s? Is the Audo CD-R a more specificly designed item? TIA for any help Chris	nzchrise (1180)

Most CD-R's with audio data when played in stereo's won't work, so thus there are Audio CD-R's which are designed mainly for audio data and will work with most standard stereo players. In all it (Audio CD-R) has a higher chance of compatability with stereo players. cheers, v.K	vk_dre (195)

No duh. look, u burn a cdr with audio data into an audio cd format, now play it in cd players (not new ones, but the older models) now it won't work. Why? The information being burnt onto the cdr disc is standard iso format. Now burn the same audio tracks onto a specifically designed Audio CDR, then play it on a cd player (not new, but older models) now it will work. Why? Because the information being burnt onto the audio cdr is standard audio iso format. Now compare the two, wot results do u end up with. Now as per my first post, it is a clear concise conclusion from wot i have posted here. Why don't u try it urself? and by cd player i mean discman, cd/stereo player, models before 2001. Some models before 2001 will be able to read the normal audio data from a cdr and will have compatability issues with certain cdr discs. I hope i made myself clear now. v.K	vk_dre (195)

Of course it is. All of my replies are just generalisations. > AFAIK an 'Audio CD-R' has a different dye in the > substrate. So. It has a diff dye, now try the experiment and see the results that u get. and of course ISO is the only format, wot i mean is that this ISO is concerned with audio data. There is no audio ISO format, it just a generalisation. I don't need to get techy. I just posted my results from an experiment i conducted.:)	vk_dre (195)
95405	2002-11-03 02:02:00	The lovely thing about standards is the way people keep "improving" on them. You are all right, and you all get a prize. The 20 year old CD standard is meant so that music publishing companies and audio equipment manufacturers can sell CDs which will play on CD players. :D The assumption was that CDs would be produced by stamping pits into a clear polycarbonate, then adding a (metal) reflecting layer (usually aluminium). This gives a usable contrast betwen pit/no pit., and the players were built to use these standard disks. Then CDs were recognised as being a very good way of distributing computer data. The basic technology remained the same. Still fine. Then people made equipment for directly writing CDs one at a time. It takes a bit more energy to write pits into metal films, and there are other problems, so the writable disks had a dye layer instead of a metal one. Various manufacturers used different dyes. These give different contrast ratios for pit/no pit. Remember that some CD-R, and CD-RW disks can't be read on computer CD ROM drives ... that's a contrast problem. People started writing their own audio CDs. The same problem. Some audio CD players have "never" been able to play audio CDs written on computers. Some CD players have been able to play "some" of them. These "Audio CD-R" disks have probably got a dye chosen to be nearest to the contrast ratio of "metal" audio CDs. (They still might not be playable on "touchy" audio players). If you need them you need them. If you don't, you don't. B-)	Graham L (2)
