Will my dvd/cd get infected if I put it into an infected computer?

i need to burn a .iso to a dvd or cd but the only computer i can do it on has been infected with malware in the past. if my computer has malware and i put a blank dvd or cd on it, will it get infected before i burn the .iso even if the checksum is accurate after the burn? It is a 1x only write which makes me think that if malware writes to it first, then the .iso shouldn't be allowed to write to it. I don't know.
