There is certainly more than one advantage to CDR over DAT (or 8mm,
whatever) tape:

1) CDRs are cheaper
2) CD-ROM drives are cheaper
3) CD-ROM drives are everywhere; just about everybody has one
4) CD-ROMs offer random access which results in *much* faster
access to specific data
5) CD-ROMs are more permanent: both in linear time (as mentioned
above) but also, for all intents and purposes, completely
immune to degradation due to use, unlike tapes. Also more
hardier in harse environments.

Now maybe we can dispense with grand generalizations and hypotheses
as to why this media was chosen and what Rocke plans to do with it.
