SCMS/MEDIA CONTROL
The first few shipments of the CD-RW700 shipped requiring
consumer CD-RDA and CD-RWDA. The original design did not call
for this, it was added at the last minute due to legal considerations
about the CD-R market. All units that shipped after March, 2000
do not require consumer media.
For the older units which required consumer media, the SCMS
code and consumer media requirements have a deep system menu
allowing these settings to be overridden. Since the legal issues
have been resolved, we are releasing the information on how to
reset your machine to use regular media.
The above is from a commercial/pro unit. The SCMS is for home units. This requires the special audio/music blanks. They also call some commercial besides "Pro" usits. A lot of these are re-branded home units, without the SCMS. Link for the SCMS used for home units, switchable on some pro units.[http://en.wikipedia.org/wiki/Serial_Copy_Management_System]
