1. First of all, you must understand what a data CD is (including data DVD). Copy audio files (such as MP3) to a CD or DVD disc. This is called a data CD or data DVD. After the burning is completed, open the disc and you can see that the files inside are still in MP3 format.

2. What is an audio CD. Use burning software to compress audio files (such as MP3) onto CD discs (DVD is not possible). This is called an audio CD. After the burning is completed, open the disc and the files inside are not in MP3 format, but in CDA format.

3. Burn data CD (or DVD), based on the capacity of the optical disc, CD disk is about 750M, while DVD is about 4G. If the MP3 file is 5M, 150 songs can be burned on the CD and 800 songs can be burned on the DVD.

4. When burning audio CDs, the recording time of the disc is used as the standard. A CD can be burned with a maximum of about 75 minutes of sound files. Based on the 5-minute duration of an MP3 song, 15 songs can be burned.

5. The car CD player or DVD player supports audio CD, but does not support data CD and data DVD. You need to read the manual.
