Yesterday one of my interns was processing a collection
and found a cardboard holder with what looks like three magnetic cards inside.
The outside label reads “Card No. 2870 Farrakhan Letter – page 1,
Card No. 2868 Farrakhan Letter page – 2, Card No. 2875 Farrakhan Letter –
page 2 w/security.” My guess is they are a precursor to a floppy disk,
although they must have been produced in 1984.
It appears that these cards were produced by the data
recording division at 3M and are probably some sort of machine readable card
similar to a floppy disk. They look like the inside of a 5 ¼” floppy
disk except they are 7 ½” x 3 1/2” cards.
Does any one know what they are or how to read them? Any
storage/preservation suggestions?
