Specify 'older'.
I have CD-R here that are 4 years old and 100% data verified.

Drop the disk drive (I did once) and forever say goodbye to your data.
And how much can a 400 GB drive store? 85 DVD? I have more then that.
Not even to mention if you have parallel drive now, in 10 years nothing will
accept that, all serial, and probably the next thing after serial ATA,
who knows.
So then keep the whole PC as backup?
maybe your monitor will be incompatible then.. Digital encrypted connection.
Maybe best is to test 'read' on those DVDs / CDRs every year or so, if you
get data errors - lots of retries - copy to new disk...
Altogether I am very satisfied with my DVDs / CDRs, there have been problems,
wit defective disks, look at the layers, if you see spots or sort of cloudy
areas, back them up (some of my old TDK CDR have that, some went back for
that).
Use good quality products.
Keep the backups in separate boxes, good humidity, temperature, out of
sunlight, do not bend of crack or use force on these, do not write with
dubious pens on CDR so the layer does not get damaged.. etc..
Common sense will go a long way.
AND KEEP A DATA BASE this is 'self discipline', and if you get more and more
the only way to ever find anything back.
Every time you burn something update the database immediately, and keep at least
2 backups of that database on different disks / memory stick, wherever.
If all else fails, tar + zip all your work, get one of those 'unlimited' free
email accounts, encrypt with some algo and key only you know, and stuff it on
their server.
