Need help with refusing blanc medium in cd-rw

The cd-rw keeps telling me “insert an empty medium” while trying to burn music and ejects teh (blanc) cd-r. Can anyone tell me what to do?

Thanks

check if cd is realle empty or try another disc (other brand).

Of course I tried several empty discs and brands. All with the same result. The cd-rw can’t read any disc, also with a full discs he ejects it saying “no medium inserted”.
I understand it has got something to do with a defect stearing system. Can anyone assist me in this?
