Do you believe that there will still be working CD-ROM
drives in
20 or 30 years time? Remember they contain custom chips as well...
Jep, I think there will still be (new) compatible drives
in consumer price range - and I bet that there are for shure
still new drives in the 'professional' price range in 20 years
from now. I don't think the drive is the problem,
new medias
are maybe a lot more difficult to aquire - try to buy _new_
_manufactured_ 8" disks - everyting you get as 'new' is at least
6 years old.
And storage systems change. When was the last time you
saw a working
Syquest 10Mbyte drive (note, the 2 on my shelf don't count, as they need
minor repairs...)
No, never had one, but what about 10 MB Bernouli Drives from Iomega ?
I still have a unit of two in working condition - now 15 years old.

them in styrofoam?
The problem is that the data is held by an
electrostatic charge on a
floating gate in the chip. It's a capacitor, really, and like all
capacitors it slowly discharges. Now, the time constant may be 10 years
or 20 years, or whatever, but it's still going to discharge.
? depending on the tecnology.
And chips - all chips - fail. If (say) the bondout
wire on one of the
data pins falls off, there's no easy way to repair it.
Yes, but a lot less and later than magnetic medias.
Oh, and putting chips in styrofoam is the quickest way
to damage them
from static. And although the damage may not be noticeable at the time,
the chip might fail 1 month later, or whatever.
