Abstract
A method is described of structuring or `freezing¿ digital encoding into a magnetic tape so that it is permanent and non-erasable. It is then shown how normal or `soft¿ magnetic encoding can also be recorded on such a tape, and ensure the integrity of the normal encoding. It is further shown how structured tape may be fixed to the cards and documents to make them secure and machine readable.
