Abstract : The patent generally relates to coded records, and more particularly to a coded tape having two conductive layers adapted to be biased to different potentials representing a binary code and a cooperating open contact sensing circuit to prevent read out from the tape in the event that a reading member fails to make electrical contact with one or the other of the conductive layers.
