If it can be played on a computer that has recorded music, it is possible that the music is recorded in a format that is not compatible with playback on a CD player.
In the case of a music CD, the format is CD-DA, and even when recording music on a CD-R, it cannot be played on a CD player unless it is recorded in the format of CD-DA.
However, if you record music in a format different from CD-DA, such as MP3 or WMA, you can only play it if your CD player supports playback in these formats. Please check the settings when recording music on a CD-R.
