I searched all over the site on this one, but didn't find this specific question addressed. I see some cd-r discs sold as "data" discs, and others for "audio". In my experience, data cd-r discs usually play fine when burned in audio cd format.
I've seen reference to those categories in these forums, but haven't seen an explanation of what the difference is. I assume that it has something to do with Red Book and/or Orange Book conventions. Any enlightenment that can be provided on this issue is appreciated. Thanks.

Audio cd's have an identification marker that is embedded onto the disk that can be recognised by consumer cd recorders. These recorders will not make a copy of copy. This applies only to "stereo equipment" cd recorders, not to computer cd burners, which by and large treat audio and data cds the same.

"Data" CDRs can be burned as whatevee you want be it Data, Audio, VCD, SVCD, blah blah blah. "Audio" CDRs on the otherhand can only be burned as Audio. Perhaps there is a quality improvement when compared to "Data"-Audio cds but i dont know.

Praetor I am not sure what equipment you are using , but I have no problem burning data or video onto "Audio" CDRs.

I'd cast my experience in with kidmd - the only difference I've been able to discern with cd-r discs whose packages are labeled "data" is just that - the label. I need to check more carefully on the orange book vs. red book convention - there may be something there. But I've always been able to burn any data discs (mp3 files mostly) onto "audio" cd-r discs, no problem.

Well I'm using an ASUS522452A 1.35 burner. The experience goes the same for other burners I've used. Of course I dont use "audio" media much, so far only TDK and I think it was Kodak... could have been Sony.... but those were audio only.

You only need buy "Consumer Audio" CDR's if you plan to use them in Standalone CD Recorders (Philips 779 etc,...). You are just wasting your money otherwise. Often the discs good quality, but only rated at 4x or 8x speed, so Error rates balloon above that.
Basically Consumer Audio CDR's are more expensive, because the RIAA takes a tax on each one, as you are going to be doing "mechanical copying" - i.e. Making up your own compilations from what you already have.

Yes, and if you try and burn a 'data' CD in a consumer hi-fi unit it says 'PROFESSIONAL?' on the LCD display.

If you use your PC for CD burning there is NO difference between audio and data CD's for burning anything i.e music, video or data - except of course the price!. Audio CD's are manufactured for certain standalone CD recorders that require that format for copying music. It's a rip-off in actual fact.

Just to reiterate what others have been saying, there is no quality difference between audio-CDRs and data-CDRs; however, if you have a standalone CD player/recorder, you may need to buy audio-CDRs because it checks for some coding on the CDR. (There's a way to trick it using a data CDR anyway.) The audio-CDR label is just more expensive because of the royalties being paid to the RIAA.

The Audio cd's are supposed to have a different geometry to the track to reduce audio errors
Data cd's should be fine for anything you are doing on the PC

emm, pigs can't fly...
If I get a chance tonite I'll try and unearth my orange book or the cd-r 'bible' to clarify my comment.
If you think about it, the geometry of the Stamper (that's the bit put in the moulding machine with which the clear blank disk with the track is made from) is different between the 74 minute, 80 min and now these 90 min disks, this means the geometry of the track between the 74, 80 and 90 min cd's are different.
Obviously more track length is added to the same diameter cd reducing the track pitch, affecting the area for the recording dye.
What I'm on about is that some of the audio cd-r had a more stable track geometry to reduce the errors associated with Audio reproduction
I use data cdr for my audio backups

How does the size thing work?
Example: if I have a CD-R that says it's 80 minutes/700 MB and the average audio quality is like around 10MB/minute, where does the extra 100MB come from? Shouldn't it be 80 minutes/800 MB?
IBM Aptiva E2N
400 AMD K6 3D processor (changed from 266 to 400 ... 66.5% increase!)
128 megs RAM
4 gig HDD
Internal: 8X Hitachi CDR-7980 (it's not a burner)
External: 4X/4X/24X USB CD-Writer+ 8200 (HP)

Awwww crap i new i should have linked that post hehe.... up in Audio, Tigre (i think) have an explaination of that... it has something to do with the fact that audio cds are measured based on 44.1Khz, 16-bit and something about sector sizes and it comes out to 800+ MB per audio cd.... in any case, you cant really compare audio and data simply because they use a different storing process.

Nah, I thought it would explain the question about how an audio CD stores 800MB on a 700MB blank. Besides it got hijacked several posts back. I just came along for the ride. ;)

How can you get around the coding and be able to use data cdr's in a stand alone burner?

audio have reduced playback margin, less jitter and play on standalone's better as that's what they're designed to do. Data cds as mentioned manuf slightly different for that reason. Good audio media will always sound better than others not spec designed for audio all other fctors being equal imho

audio and data cd-r are the same
read the posts above
audio is manufactured in the sam way as the data, the only possible change would be a different stamper with slightly different track geometry for audio.
in practice the stampers and production process are identical

Dont forget PC burners vs standalone audio burners.
