If I'm not mistaken, these are merely iron wires that have axial twists put in them (by mechanically twisting the wire). They were once proposed as a medium for encoding the magnetic stripe of credit cards. Their advantage would be that the magnetic anomalies created by the twists could not be erased and re-recorded, unlike conventional magnetic recording media. As far as I know, this proposal never got anywhere.
