YEs, it's magnetic, yes it writes too. It
puts 3 data tracks nad oen
timing track on the card, you put one end fo the card in, then turn it
round and put the other end in to get twcie the capacity (in other
words it only uised half the width of the card at a time. It's a pity
you didn't get any cards, those are not easy to find.
I've noticed bags of blank cards showing up fairly regularly on Ebay.
