There are several CD-making maschines, having internal Harddisk
and CD-Burner, which emulate a SCSI-Tape 
(for example, they claim to be an exabyte)
So you dd the image to the CD-Maker.
To burn it (that is: Transfer from internal HD to the CD-Burner, 
some Consistency checks? (that's my fsck...)) you must
initiate an additional Command. To be able to live without extensions
to do so, they use standard Tape-Commands like "fsf"
