You can't write to a CD-ROM. Just to remind, the RO part stands for
"read-only". There is such a thing as a CD-ROM burner (for people with
$many) which will write whole CDs at a time on special writeable
blanks, but this is still write-once - you can't change it thereafter.
[at a push, these will do multiple "sessions" on one CD, sequentially,
but for technical reasons, you lose a number of megs per new "session"
apart from whatever it is you want to write]. If you want to use one
of these, I believe (being far too poor to own one myself!) that they
generally need their own, proprietary software, which will probably be
sold seperately to you for another $many.
