Hallo welcome to just answer.
I would like to know few things about this problem:-
1. Have you ever been able to successfully record on this system before?
2. Have you ever recorded on this batch of disks before?
3. What is the manufacturer and model of the disk that you are trying to record to.
What error are you getting?
Do you have a computer with cd drive?
If yes can you try to read the cd in question?
Can you tried to read a regular cd on this system to see if you can get it to work?
