Abstract

A method of recording machine-readable security data on a record medium, such as a cash dispenser card, is described in which the security data is deposited on the record medium as a sequence of magnetic characters. The characters may include a first magnetic character which when scanned in a given direction by a magnetic pick-up head having a sensing gap generates a characteristic signal exceeding a first threshold level in a positive direction but not exceeding a second lower threshold level in a negative direction, a second magnetic character which when scanned in the said given direction by a magnetic pick-up head having a sensing gap generates a characteristic signal exceeding the second lower threshold level in a negative direction but not exceeding the first threshold level in a positive direction, and/or a third magnetic character which when scanned in the said given direction generates a characteristic signal exceeding both the first threshold level in a positive direction and the second threshold level in a negative direction. The first and second characters may comprise left-handed and right-handed right-angled triangles respectively and the third character may comprise a rectangle. The invention permits the recording off of any desired binary sequence by arranging that the first character represents a binary "1" and the second character represents a binary "0".
