摘要

A magnetic card (10) has a base card (11), a magneticstripe (12) formed on the base card (11), and a pluralityof 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 aplurality of unit magnetic segments (12a) each having arecording capacity of a predetermined number of bits, forexample, eleven bits. The optical fibers (15) are assignedto the unit magnetic segments (12a), respectively. Aread/write head (23) reads magnetic information from themagnetic stripe (12), an optical read device including alight-emitting device .(20) and a light-receiving device(22) read optical information from the optical fibers (15),and a controller (25) examines the magnetic informationwith reference to the optical information to authenticatethe magnetic information.
