In 100 years it'll be like a cylinder record.
Yeah, my dad still
has cylinder records and a player, as do museums.
Lots of collectors as well. They are not all that uncommon in working
condition.
As I've said several times before, I think I could make a cylinder player
(or a disk-type reocrd player) from scratch in my workshop. I doubt I
could do the same for a CD or DVD of any type.
