Absolute compatibility.

The Optical Storage Technology Assocation (OSTA) has announced a specific compatibility, called Multiplay ensuring for all Compact Disc Recordable (CD-R) and Compact Disc ReWritable (CD-RW) discs can be played on CD players and DVD adhere to the standard. It is particularly important to the attention given to compressed formats (such as mp3 or wma) for which it is established a new format logical disk, called CDA (Compressed Digital Audio), so that, if adopted wide-ranging, should make it compatible players with all sizes currently available.
