CD-ROM archiving

[Seth J. Morabito]

Hey folks,

Does anyone have any guidelines about making archival images of
CD-ROM media?  For years, I've been using dd on Solaris or Linux
to dump the raw bytes of CD-ROMs, and cdrecord if I want to make
a copy from the raw image, but I don't know if this is considered
"good enough" to preserve all the associated filesystem and partition
structures of the disc.  It has been for me, so far, but I'd like to
hear other opinions on the matter.  How do you archive CD-ROM images?

Does anyone use any special software or have any tips?
