Disks as a Roll Conservation Medium
By Jim Gallops

Personally, (and this is from experience), if you recopy the data on your
floppies every couple of years to another floppy (or other medium) things
should be fine.

As an example, I have had many Violano rolls that I have been archiving in
an obscure format on 8 inch soft sectored floppies. These rolls were recorded
before the advent of PCs and MIDI. (How many 8 inch floppy drives have you seen
lately?) So in order to protect the 60 or so disk I have, I migrated the
contents to 5 1/4 inch disks after a few years. Again, after 3 1/2 inch media
came out, I migrated to them. Right now, I am in the processes of burning
the data onto CD-ROM.

Because digital data is so easy to replicate, the life of the media should
not be a problem as long as copies are made on a regular basis. The real problem
as I see it is what does the data mean. As an example, if I gave you a copy
of the Violano rolls that I have archived, you would have great difficulty
in figuring out what the data means and how to get it to play. So, I have
written a description with the data of how to interpret it. It would be
a shame if the data survives, but the format is unknown.

25 years from now will MIDI SMF Type 1 (or 0 or 2) still survive? If so, will
there be documentation to explain it. (Lets hope so.) So, I try to put
an explanation of how to interpret the data with it. So many of the things
we call "Standards" today are short lived; especially in the computer world.

Just my 2 cents worth.
