Cd player doesn't play mp3 files recorded on cd

no,only pre recorded discs

MP3 players can only play music files in mp3 file format.1st - You need to convert your CDs to mp3 music filesonto your computer or download them from the Internet and then copy them toyour MP3 player.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.
There are also Freeware CD RIP programs on the Internet that add the musictitle and album title to the mp3 file automatically.
OR
Download mp3 music files from the Internet to your computer, some sites willcost money to download these music files.
2nd - connect your MP3 player to your computer using the supplied USB cable.The computer will see this player as an external storage device, Just copy theMP3 music files from the computer's hard disk to the MP3 player.I suggest you create a album/title folder for each CD soyou can place the mp3 music files by that artist into that folder. Then copythese folders to your MP3 player and you will be able to select and play yourMP3 music by selecting the album you wish to play.
NOTE - When the USB cable is connected to the computer, it will also charge theMP3 player's battery.Click on this link for instruction on converting musicfiles to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files

If you are attempting to burn mp3 files as an audio CD, then that's the problem. You cannot burn audio CDs from MP3 files. You have to burn MP3 files as a data CD and not as an audio CD. See excerpt taken from page 33 in the CDR420 user guide. "Prepares CDs that can be played on standard CD players. Compact Disc Digital Audio (CDDA) uses uncompressed PCM, .wav files. The CDR420 does not convert MP3 files to PCM so MP3 files are ignored if you choose AUDIO as the CD TYPE"

You can do this with your PC. Download a program called Audacity. It's free. With it, you can record audio from your Line IN connector. You'll need to connect your cassette player to the Line in on your PC. Start Audacity, set it to record and play your tape.

If you want to save the files as a .mp3, you'll also need to download the LAME mp3 encoder. In any case, when you have the file recorded, export it as a .mp3 or .wav and then use your CD burning program to create the CD.

the mp3 files have to be recorded in the ISO9660 level 1 or level 2 format, or the Joliet or Romeo in the expansion format.
Please note this is verbatim, straight from my Sony manual.
For details of your recording format you will have to see your converter's help or configuration files.

In your application program is where the determination of audion verses application is made. Read you manual to determine how to select the proper settiings.

First, try to copy the files to your PC. Make sure you have a CD burning program and drive of some kind. WAV files are very large compared to Mp3 files, so you may be only to fit a few on an AUDIO CD. If you burn the WAV files to CD as a DATA CD, then you will be able to fit more files onto a single CD, but you will not be able to play that same CD in a CD player.
