Not sure what you are asking.....Try typing in the make/model in to yahoo.com and ask 'who ever' made the radio.........If not cleaned disks will and do get stuck...Again, depends on the make but you can some times open it with a pin (there's a small hole where the disk ejects from). Some times, if not clean or the disk is dirty or old this will cause it to happen. For future use...think of buying a disk cleaner.
