Abstract

PURPOSE: To increase a magnetic recording part by providing plural pieces of concentrical or spiral magnetic recording bands on the outer periphery in the central part of the card and using the card by rotating the same.
CONSTITUTION: An aperture 2 is provided in the central part of the ordinary PVC card 1 and further plural pieces of the magnetic recording bands 3 are concentrically provided at equal intervals on the outer periphery thereof. A plastic coating is applied thereon. The recording bands may be formed not concentrically but spirally on the outer periphery of the aperture 2 at the center. The provision of the magnetic recording bands on both sides is possible if the coating is provided on both the sides. A rotating device which inserts a revolving shaft into the aperture 2 provided at the center of the card 1 and rotates the card around the shaft exists in a card reader and the magnetic recording part moves in parallel while rotating when the card is rotated. Information is thus read. The capacity of the information is increased in this way.
