                                                          Depends.There are different CD types.
  
 A normal CD can not be used again.
 A CD-R (compact disc recordable) disc can only be used once ,
 so they are pretty much useless after you put something on it.
 
 A CD-RW disc on the other hand can be formatted and used again ,
 however ,fewer CD players can read them.
