An average CD will hold about 700 MB of data. I can easily fit 10 albums onto that if I burn it onto a CD as data. Why, then, can I only burn 1 album (duh, a cd is an album) on a CD formatted for audio.
What's so special about an audio CD that makes the audio tracks on them so "big", and why won't a data CD play in a CD player? Does the formatting really make all that much of a difference in file sizes on a disk?

.cda files are bigger because it can be played on most CD players and like a codec and a CD player can only read one codec. So for some reason its bigger.
.mp3 is another codec, And is compressed smaller, And would only work on some CD players (like mp3 players). That's why it is smaller.
Good luck and i hope this helps.

The answer is CD audio is not compressed, and there's a LOT of additional checksums and error recovery code in the format to ensure that even scratched discs can be played.
If you burn to CD as data, you're doing it as MP3, which is a HEAVILY COMPRESSED format, and requires a DECODER (or codec) to decode. Pure CD audio is a simple format that doesn't need any decoding. MP3 is also a "lossy" format that relies on getting rid of information that most humans cannot hear. Some audiophiles swear they can hear the difference, but then, most of us can't.
And finally, there is NO SUCH THING as a CDA format. CD Audio (Redbook) stores data in the "Red Book" format. CD-ROM stores data in the "Yellow Book" format, which is basically Red Book with smaller sectors (more of the space dedicated to checksums). Microsoft started the practice of making up the .CDA extension to make audio CD visible to the CDPLAYER app in Win31. The fact that you can't WRITE a "CDA file", which should clue you in that it doesn't really exist.

I always burn music as "data" files and you are correct in that there is no limitation as to the total number of files you can include. Nero restricts me to 99 files if I make a music cd and I can get approximately 175 on a data CD. So do what I do and make data CD's if you are archiving or backing up your MP3 files.
Raw music files are very large. 40M is not unusual at all. MP3's are compressed versions of the raw files and do not include every audio aspect of the original file. However, for the vast majority of people with normal hearing, the MP3 is more than acceptable for listening unless you are an out and out "purist" and have to have the full up file.
A data CD will play in the CD/DVD drive with no problem. You have to set the CD/DVD drive up in My Computer to "play" the CD when it's inserted. Here's how you set it up.
Music Disks:
To have a Music (Data) CD launch when inserted into the drive Click on My Computer icon to bring up the new window.
Right Click on the selected drive
CD drive > Properties > Auto Play tab
Select “Music Files” from the drop down menu under “Select content type…”
Click the radio button in the “Actions” box to “Select an action to perform…”
Hope this helps.

Digital files (mp3, wma) are compressed. When you burn a CD, the song is recorded in a way that a CD player can read. This takes up a bunch of the CD. When you format a CD and put music files on it, the music is digital and compressed, but it can't be read by most CD players because players can't process files like a computer can.

in case you're making an "audio cd" (a typical cd which may be performed in any cd participant) then it will purely be waiting to hold eighty minutes... uncertain why regardless of the undeniable fact that it is the format. regardless of the undeniable fact that, those days surprisingly much all new cd gamers can play "mp3 cds" with an mp3 cd you ought to use all seven-hundred mb on the cd. purely fill it up with mp3s by ability of burning the cd as a "information disk" or "mp3 cd" making use of your burning software. *observe as reported till now that those form of cds will purely be playable on cd gamers that may playback mp3 cds.

.cda files are bigger, and i think they are based on the exact constant speed of the player, not the actual quality.

cda (wma) files are much bigger than mp3
