A DualDisc is a two sided disc product 
which mates DVD recorded material on 
one side with digital audio material on the 
other side. However, since the audio 
material side does not conform to the 
Compact Disc (CD) standard, playback 
on this product is not guaranteed.

In some cases, CD-Rs/-RWs cannot be 
played back on this system due to the 
recording quality or physical condition of 
the disc, or the characteristics of the 
recording device and authoring software. 
The disc will not be played back if it has 
not been correctly finalized. For more 
information, see the operating 
instructions of the recording device.
