So, what you have is a player or recorder?
What interface does it have to transfer the data> USB or audio? I guess what I am asking is what model is it?
What you need is software to transfer the music files to the player/recorder, since this is not a standard cd to be burned.
I have a Sony minidisc recorder/player, with the plastic encased mini-cd's. What I need is an audio card that can record the music via an analog or digital signal output. Have not tried ths yet with Linux, but I recently aquired a sound card that can do the digital transfer.
Let's see what you have and perhaps someone has the answer.
