Abstract

PURPOSE:To constitute an inexpensive and simple card reader, by providing read and write exclusive heads adjacently on the surface and the reverse side of a card so as to be symmetrical to the center of the magnetic card. CONSTITUTION:On the left end part of a surface 2 of a magnetic card 1, a slender data channel magnetic stripe 3 is provided, and on the left end part of the reverse side of the magnetic card 1, a slender clock channel magnetic stripe 7 is provided. A write exclusive head 10 is provided adjacently on the surface of the magnetic card 1, and a read exclusive head 11 is provided adjacently on its reverse side. Distances between both the heads 10, 11 and the magnetic stripes 3, 7, and the center line of the card are set to a=b=c=d. The magnetic card 1 is inserted 12 into a card reader with its surface up, and new data is written 10 in the data channel 3, reading out 11 a signal of the clock channel 7. When reading out a signal of the data channel 3, the magnetic card is inserted 12 into the card reader with its reverse side up.
