Abstract

PROBLEM TO BE SOLVED: To prevent magnetic recorded data on a magnetic prepaid cared from being erased and rewritten by applying a magnetic coating onto a made material, encoding the magnetic recorded data in the not dried state of a magnetic coating film, immediately drying that film, and fixing the magnetic recorded data. SOLUTION: The magnetic ROM card is composed of a card base material 1, magnetic recording layer 2 and fixed end mark 3. First of all, the magnetic coating is applied onto the card base material 1, the magnetic recorded data are encoded in the state where the magnetic coating film is not dried, then that film is immediately dried, and the magnetic recorded data are fixed. Thus, the magnetic recorded data are prevented from being erased and rewritten, at the same time, the fixed magnetic recorded data have frequency signals or the start mark and end mark of the fixed magnetic recorded data, and the magnetic recorded data are provided between both the marks. Thus, the illegal use of a used magnetic prepaid card is prevented.

2. Description of the Related Art In recent years, magnetic prepaid cards are rapidly becoming widespread and the fields of application are expanding. However, forgery of used magnetic prepaid card,
The current situation is that there is no end to problems caused by falsification.
The reason for this is that in a conventional magnetic recording medium, a magnetic coating material is applied onto a base material, magnetic field orientation is performed in a constant magnetic field, and the magnetic coating material is dried and fixed through a drying furnace. Since the magnetic recording data is encoded using the magnetic recording medium manufactured in this manner, it is possible to erase and write the recorded magnetic data. Therefore, it was possible to erase and rewrite the magnetic data in the magnetic layer of the used prepaid card and to use it illegally.

In a conventional magnetic recording medium, a magnetic coating material is applied onto a base material, magnetic field orientation is performed within a constant magnetic field, and the magnetic coating material is dried and fixed through a drying oven. Since the magnetic recording data is encoded using the magnetic recording medium manufactured in this manner, it is possible to erase and write the recorded magnetic data. This means
Although the magnetic recording method has an advantage that it can be repeatedly used, it has a drawback that it can be illegally used by erasing and rewriting the magnetic data of the magnetic layer of a used prepaid card. The present invention has been made in view of the above situation, in which magnetic recording data is coated on a substrate, magnetic recording data is encoded in an undried state, and immediately dried to obtain magnetic recording data. Fixing makes it impossible to erase and rewrite the magnetic recording data, and at the same time, the fixed magnetic recording data is a frequency signal or the start mark and end mark of the fixed magnetic recording data are set. In the meantime,
A magnetic ROM card characterized by having writable and erasable magnetic recording data by a conventional method, and magnetic recording of a magnetic prepaid card by destroying the magnetic recording data fixed after use or after use. By making it impossible to erase and rewrite data,
It is impossible to falsify or illegally use a used magnetic prepaid card.

In order to achieve the above-mentioned object, a magnetic ROM card according to the present invention has a magnetic coating material coated on a base material, and the magnetic coating data is recorded in a non-dried state. It is characterized by encoding and immediately drying to fix the magnetic recording data, and at the same time, it is a prepaid card that reduces the fixed amount of money each time it is used, as seen in the examples of telephone cards and pachinko cards. Is for pre-encoding the required frequency as fixed magnetic recording data and destroying the pre-encoded frequency signal each time it is used. Furthermore, when the amount of reduction of the prepaid card is indefinite, it has a fixed magnetic recording data start mark (may be the face value of the prepaid card) and an end mark, between which writing and erasing by conventional methods are possible. Has a magnetic recording data layer,
The amount data is recorded in the magnetic recording data layer, and the balance is magnetically recorded each time the prepaid card is used. It is characterized in that the magnetic recording data of the fixed start mark and end mark of the magnetic recording data is destroyed when the remaining amount becomes 0 or becomes a fixed amount or less. As a method of destroying magnetic recording data, there are a mechanical method such as punching and polishing, and an electrical method such as discharge destruction.
