The CD optical disk would have to be ST-506/MFM compatible.  If it's not, 
then you can pretty much forget it.  When and *if* the 3B1 ever sees a
SCSI interface, those opportunities will open right up.  Most likely
the CD technology quoted here was for the 3B2 SCSI products.   I'd pretty
much impossible to get 650MB using MFM recording.
