Difference in media ?!?

[91BRAVO]

I have a constant debate with my mates here at work:

Is there a difference between "Audio" CDR(W)'s and "Data" CDR(W)'s?

My claim is that the ONLY difference between the two is the packaging and labeling. There is NO quality/limitation difference between the two.

If you know of some 'Credible' web sites or other sources that I can use to proove (or to disprove) my theory please post!

I have to agree with you. A music CD is in reality a data CD...

[mike416]

the only difference between them is that the audio cd uses layer that supposedly to "agree" with standalone cd player and will have less problem when you create it with standalone audio cd recorder

Take a look at this ng post, it seems to accurately explain the differences in audio cdrs in depth:

Exactly.

There are REAL differences between an audio CD-R disc and an ordinary CD-R disc. This difference is what stops you from using ordinary CD-R blanks in an audio CD recorder.

There are no other significant differences other than perhaps price. Advertised statements claiming otherwise are dubious at best.

Thanks,

Another Question if I may:

Does it make a difference in burning speeds when authoring a (S)(X)VCD?

Whew, talk about opening a can of worms, I wont use the usual "do some searching first before posting bit" on this

"Does it make a difference in burning speeds when authoring a (S)(X)VCD?"

You are going to get 50/50 on the yes & no of this question, in the end, it will boil down to one of those things you will have to try for yourself...because of the major contributing factors: media, CD burner, & standalone player...certains combinations will result in poor play if burned at high speeds, and other combinations will not..it will depend on which combination you have that will work best for you.

[vitualis]

My understanding of this is that it "depends".

If your DVD player is designed to read CD-R and CD-RW media and reads just about everything (i.e., a multiread drive), the answer is NO, burn speed does not matter. You can burn as fast as you like (assuming that your drive can handle it and you don't have dodgy media).

If you DVD player is not designed to read CD-R and CD-RW media or reads them poorly (e.g., some brands work, some don't), then burn speed can make a difference. Plenty of people have posted this phenomenon in the past.

from what I understand the "audio" cdrs have a little code in them that tells the standalone copy machine that it is a music type cdr. but in a computer it really makes no difference, but why buy a music one they are more expensive, the data ones you buy from the store are alot cheaper.

Very (Read very,very,very ) ocassionally, it can produce an unplayable disk if you use a certain burnspeed with certain media (even rarer to produce unplayable disks because of the burnspeed alone). By varying burnspeed and media, certain combinations can cause a burner to produce more errors. However, these errors are no way near enough to actually cause the data to become corrupt.
Nowadays, with the new technology it is very uncommon for burnspeed to matter and only really happens with old CDRW drives. There is an optimal burn speed for every drive because the process of burning CDR is non-linear, at the end of the day though the difference is negligable at the best of times (The difference then will be only noticable if the CDRs are compared byte by byte).
If you have a fairly recent CDRW drive then confidently use whatever burn speed you wish, just choose media carefully. The media is far more important to get right.

BTW, I have an old CDRW drive: Some PS games that I burn at 4x become unplayable, using any media. This only happens with PS games though. Strange.


devinemi83,
People with a HiFi CD burner have to use the special CDR Audio disks as the standard data disks dont work. Not everybody who burns CDs does so with a PC, a PC is a very expensive way of burning CDs compared to a HiFi burner.
