Abstract

PURPOSE:To enhance the effect of preventing falsification by providing pattern layers which are patterned by using magnetic ink having different magnetic characteristics on a magnetic recording layer and a concealing layer which covers the pattern layers. CONSTITUTION:The magnetic card is constituted of the magnetic recording layer 2 on a card-shaped substrate 1, pattern layers 31 to 33 formed to desired patterns by using two kinds of the magnetic ink and ordinary ink having the different characteristics, the concealing layer 4 provided on these layers 2 and a protective layer 5 provided thereon. PET, PVC, paper, etc. are used for the substrate 1. Pattern layer 33 is used as a dummy layer. The layer 4 is formed by vapor deposition of metals, such as Al to conceal the layers 31 to 33 to avert the visual identification thereof. The patterns of the layers 31, 32 are read by the bias value A of the magnetic head and only the patterns of either one are read by utilizing the difference in the output level of the magnetic ink forming the layers 31, 32 by the bias value B at the time of reading the recorded information of the pattern layers 31 to 33.

Also, at the bias current value B of the magnetic head, the pattern layer 31. Utilizing the difference in output level between the magnetic ink (1) and the magnetic ink (2) forming the pattern layer 32, only one of the patterns is read. Here, when Company A and Company B issue magnetic cards respectively, the pattern layer 31 is printed with magnetic ink ■ on the exclusive magnetic card used by Company A, and the pattern layer 31 is printed with magnetic ink ■ on the exclusive magnetic card used by Company B. Print the pattern layer 32 with magnetic ink (3). In addition, this example was applied to magnetic cards shared by companies A and B, and magnetic ink was
By printing the pattern layer 31 with magnetic ink (2), printing the pattern layer 32 with magnetic ink (2), and further printing the dummy pattern layer 33 with normal ink, the card becomes a magnetic card that can be used by both companies A and B. . Incidentally, the exclusive magnetic cards of Company A and Company B have only the pattern of the pattern layer 31 made of magnetic ink ① and the pattern of the pattern layer 32 made of magnetic ink ①, so they cannot be used by companies other than their own companies.

Therefore, two types of magnetic ink with different magnetic properties are used, and two types of signals are used, one for each pattern only and the other for the magnetic ink, so it is difficult to determine which magnetic ink is used. It's easy to lose track of who's there. As a result, the recorded information becomes unrecognizable, making it possible to significantly enhance the anti-counterfeiting effect. Furthermore, it is possible to provide three types of pattern information on one magnetic card. That is, it is possible to have pattern information for only magnetic ink ■, pattern information for magnetic ink ■ only, and pattern information for magnetic inks ■ and ■. Furthermore, pattern layers 31, 32° 33 and magnetic recording layer 2
