All CD recorders that write CD-R and those that write CD-R and CD-RW can record an audio CD (or compile several tracks from several audio CDs). However, not every audio CD player (especially the older ones) will play CD-R media (though most will).

You may have the writer on a higher SCSI ID than the scanner. The scanner should be on an ID at least two higher than any recorder you have. The scanner is the slowest device on your chain, therefore should be set to ID 6.

Unfortunately No. No recorder on the market as yet can copy more than 99 audio tracks onto a CD. 99 is the maximum number of tracks with which Red Book copying can cope. Several hundred or even 1000's of MP3 files can be burned to a CD.

It is possible to burn MP3 files to a CD. However, as MP3 files, they will not play on a regular audio CD player. The files need to be converted from MP3 to WAV and then recorded to CD. The software package that we sell called Nero Burning ROM does this very well. (Of course, you do not get the advantage of the compression in MP3 when converting those files.) CDs with MP3 files can be played on MP3 enabled CD players.

Most audio CD's have a total capacity of 74 minutes or 650 Megabytes of binary data. Each byte is represented by 8 bits (a bit being a binary representation of either a 1 or a 0 - take a look at the power switch on your PC and you will see it is either ON with a 1 or OFF with a 0). So only 1's or 0's are used and not other numbers such as 2, 3, 4 etc. If you multiply 650 million by 8 then you have the total number of bits of information used to represent 74 minutes of audio.
