For those who need to archive small amount of data, (such as tax, medical
records, quarterly reports, annual reports, =85.) 650 MB may be sufficient.
Currently, most of the WORM drives are in that capacity range.

The current design already incorporates a 1 GB hard drive with the CD-R

This sounds like that the CD-R should work as a tape drive, which a backup
can expand to multiple disks. This can be done, by writing to the CD-R
directly with reduced capacity (~450MB), or staging on the hard disk (up to
650MB0 before writing to CD-R (which takes about 50min). But this does not
have the advantage of accessing data directly, which can be useful for=
auditing.
One more side feature, the CD-R will be formatted to ISO-9660 standard. The
MPE disk volume will appear as a huge file. With some software to decipher
MPE file structure, files can be accessed from PC.
