data cd vs music cd

if i want to burn mp3 to a cdr disk, what is the diference between
these 2 ways of burning a disk?

Music CD is a regular CD Redbook format up to 74 or 80 minutes, should play
on any type of CD player.

An MP3 CD is a data CD of MP3 files - depending upon compression level it
can hold maybe 8 to 12 hours of music. It will play on a computer, an MP3 CD
player, or most recent DVD decks.

You've asked two different questions. First (it seemed) you were
asking about a burning method, now you're asking about different media.
For a computer, there's no difference between data CDs and music CDs.
I'm just talking about the media itself now. Music CDs are meant to be
used in standalone CD copiers. There's some code on a music CD that
says to the copier that everything is cool... data CDs don't have that
code and they won't work in a standalone copier, but either will work
in a computer. Because the standalone copiers do nothing but copy Audio
CDs, there's a built in fee in the price of music CDs that goes to the
music industry in some manner.
In your initial question you said something about "burning method",
which sounded like you were asking about the difference between burning
a data CD vs. burning a regular Audio CD from mp3 files. When creating
an Audio CD from mp3s, the mp3s are first decoded to .wav files, and
then those .wavs are used to create the tracks of an Audio CD.

Data CD = space used equal to what they use on your HD

Audio CD = MP3s decoded to wave, space used = 10+ MB per minute of
playing time.

Stated another way, making an audio CD from 10 MP3s could use the entire
capacity of the CD. Making a data CD from the same 10 MP3s would only
use a small portion of ther total space available on the CD.

Since the question was already answered with respect to the
formatting, I presume you mean the physical discs themselves:

The ones marked for audio have a higher media levy and licensing fee,
making them more expensive. They also have a header that specifically
identifies them as an audio CDR. The audio-CDR header only makes a
difference if you're using a stand-alone audio CD burner, as those
decks specifically look for that header before allowing you to use
them.

If you're using a modern CD burner in a computer, the only difference
to you is that you're paying more for the audio-CDR. The audio-header
does not prevent it from being used as a data CD. However, as the dye
is formulated for a slower speed, you may be limited to slower speeds
on your drive. There's also probably a pretty steep mark up for
audio-CDRs, as the price difference is much larger than can be
accounted for by the increased levy and CD licensing fees. (locally an
audio-CDR averages $2-$4 Cdn, where a similar quality name brand
general purpose CDR is $0.50 Cdn or lower).

If you're burning in a stand-alone CD burner, you can only use
audio-CDRs because the general use CDRs (what you might be calling
data-CDRs) won't be recognized by the burner unless you install a
hacked firmware. It is not possible to modify the discs to add that
header, as computer burners are incapable of burning a fake audio-CDR
header onto general use discs.

If you're burning in an older burner that has compatibility problems
with the more recent high speed media, the audio-CDRs are rated to
burn at 1x (the speed of the stand-alone burners). Since "slow-speed"
CDRs are pretty hard to find, your options in such a situation are
either buy a new drive, or use the more expensive audio-CDRs.
Realistically though, such a drive would be more than a decade old,
and the low cost of even DVD burners (also capable of burning CDRs)
means it is much more cost effective and reliable to replace the
drive.
