They do need a supplementary software to record Nero's version in called In CD as I recall -[or 'packet writing' elsewhere]
The recording as such will play back on the machine the recorded it or on an other machine with the software.
DVD players do play them if the disk has been 'Finalized' but once finalized cannot be over written
When these camesout it was visualized to be used as a giant 'Floppy disk' but nowadays 'Flash Media' has taken on that role.
The general perception is to disregard RW disks as surpassed technology- just as a floppy is.
