In addition, a rotary magnetic card is provided in which a rotating hole is formed in a rectangular flat card body, and a magnetic recording band having a concentric recording area is provided on the surface of the card body with the rotating hole centered on the rotating hole. Writing for a rotary card, comprising a rotating turntable and a head that writes and reads information by moving in a direction transverse to the rotational direction on the magnetic recording band of the card on the rotating turntable.・
This is achieved by a reading device.

[Effect]

In the present invention, as a rotary magnetic card, by providing a magnetic recording band having a concentric recording area around a rotating hole formed in the card body, the number of concentric recording areas increases, and a large amount of information can be recorded. It becomes possible to do so. In addition, as a writing/reading device, the rotary magnetic card described above is rotated on a turntable, and the head is moved over the magnetic recording band in a direction transverse to the direction of rotation to write and read information.
