What is the difference between CD-R and CD-RW?
CD-R blanks have a completely different coating than CD-RWs. On a CD-R, bumps are burnt into the coating. That can be interpreted as a '0'. CD-RWs have a crystalline coating that changes its appearance when it is hit by the laser. The strength of the data (and also of the protection) is weaker on a CD-RW. This leads to the phenomenon when the copy on a CD-RW can be used, while the same copy on a CD-R does not work.
