A magnetic card (10) has a base card (11), a magnetic stripe (12) formed on the base card (11), and a plurality of optical fibers (15) extended within the base card (11) substantially perpendicularly to the magnetic stripe (12). The magnetic stripe (12) consists of an arrangement of a plurality of unit magnetic segments (12a) each having a recording capacity of a predetermined number of bits, for example, eleven bits. The optical fibers (15) are assigned to the unit magnetic segments (12a), respectively. A read/write head (23) reads magnetic information from the magnetic stripe (12), an optical read device including a light-emitting device (20) and a light-receiving device (22) read optical information from the optical fibers (15), and a controller (25) examines the magnetic information with reference to the optical information to authenticate the magnetic information.

Une carte magnétique (10) est constituée d'une carte de base (11), d'une bande magnétique (12) formée sur cette carte de base (11) et d'une pluralité de fibres optiques (15) s'étendant dans ladite carte de base (11) dans une direction essentiellement perpendiculaire à celle de la bande magnétique (12). La bande magnétique (12) est constituée d'une pluralité de segments magnétiques (12a) ayant chacun une capacité d'enregistrement fixée à un nombre prédéterminé de bits, onze bits par exemple. Les diverses fibres optiques (15) sont individuellement affectées aux segments magnétiques (12a). Une tête de lecture-écriture (23) lit l'information enregistrée sur la bande magnétique (12), un dispositif de lecture optique comportant un dispositif luminescent (20) et un dispositif récepteur de lumière (22) lit l'information transmise par les fibres optiques (15) et un contrôleur (25) authentifie l'information transmise par la tête de lecture-écriture magnétique en la comparant à l'information transmise par le dispositif de lecture optique.
