CD-RWs required more sensitive optics on the part of the playback
device, CD-Rs however once they were written with PCM audio data
(_not_ mp3 files) and finalized IIRC were essentially the material
equivalent of a commercial Red Book audio CD and should work on any
CD player, even ones from the 1980s.

Actually CDRs are much less reflective than 'pressed' CDs and as such some
older CD players don't have the laser power needed to get a good (reflected)
signal.


** CDRs use the same metallised ( Gold or Silver) reflecting layer as a normal CD.

They play perfectly in my 1982, Sony CDP101.
