Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application of the Present Invention in TL Business The present invention relates to a recording card used in public telephones, ticket vending machines, and the like.

<Prior art> (Figures 4 and 5) Public telephone gI! As shown in FIG. 4, the recording car 1, which is often used in I machines, ticket vending machines, etc., has a recording layer 3 made of a magnetic material on one surface of a flat rectangular substrate 2. A recording track 4 on which information is previously written in the longitudinal direction is formed by an information writing device or the like.

Is this recorded information, for example, public? ! In the case of a recording card used in a 2-talk machine, etc., fixed data such as IO information, issue number, and date of issue are used to identify the validity of this recording card, and variable 1iIliWi data that is updated each time it is used. It is configured.

Therefore, such 2! When using the device using the record card 1, as shown in Fig. 5, the card processing I! ! ! In the device 5, by bringing the magnetic head 6 close to the recording track 4 and moving the recording card 1 relatively in the length direction, the information recorded on the recording track 4 can be read from the magnetic head 6. IFi (fixed data and variable VfJ value data) is provided.

The validity of this recording card 1 is identified by the read information, and the device can be used (for making calls, etc.). When the use of the device is completed, a value corresponding to the frequency of use is decremented from the read variable value data, and new variable value data is obtained.

This new variable (IIhri data) is transferred to the area of the recording track 4 where the hyperbolic variable value data was recorded via the magnetic head 6 when the recording card 1 moves relative to the magnetic head 6. I'm drawn in.

In addition, in order to confirm whether this data has been rewritten correctly, the recording card 1 is moved relative to the magnetic head 6 again, the data is read by the magnetic head 6, and the rewritten data is confirmed. After that, the recording card 1 is returned.

Incidentally, such linear relative movement of the recording card 1 with respect to the magnetic head 6 is performed by forward and reverse rotation of a motor (not shown) or the like within the card processing device 5.

<Problems to be Solved by the Invention> However, in the conventional recording cards as described above, a recording track in which information is recorded linearly in the length direction of the recording layer of the recording card is formed, and this recorded information is In order to read, rewrite, and confirm the recorded information, the recording card is linearly moved by rotating a motor or the like in the card processing device in forward and reverse directions.

Therefore, the information recording range is determined by the length of the recording layer of the recording tJ-de, and the information bar is small compared to the overall size of the recording layer, so it is said that it is not possible to record much information. There was a problem.

Furthermore, since the recording card is transported back and forth in a straight line in order to read, rewrite, and confirm information, there is a problem in that the processing time is long.

<Object of the present invention> The present invention was made in view of the above circumstances, and an object of the present invention is to provide a recording card that has a large amount of information and requires short processing time for reading and rewriting information. .

Means for Achieving the Object> In order to achieve the above object, the recording card of the present invention has a recording card in which information such as ID information is previously recorded in a circular or arc shape on at least a part of a flat rectangular substrate. A track is formed.

For this reason, the information recording range becomes longer and more information can be written, and this recording card can also be rotated.
Since information can be read, rewritten, etc., the processing time can be shortened.

An embodiment of the present invention (Figures 1 and 2) Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an example in which the present invention is applied to a magnetic card such as a telephone card as a recording card.

, in the figure, a rectangular flat substrate 12 of a magnetic card 11
A recording layer 13 made of a magnetic material is provided almost entirely on one surface of the recording layer 13, and information is written on the recording layer 13.
Depending on the location, etc., a recording track 14 on which information is written in a circular shape is formed in advance.

The information written on this recording track 14 is composed of fixed data for identifying the validity of this recording card and variable 1iIliVi data that is updated each time it is used. As shown in FIG. 2, a recording card 11 is held on a turntable 21 of a card processing device 20, and while the turntable 21 is rotating, a circular shaped The information is recorded in a fixed area 14a and a variable area 14b on the recording track 14.

Therefore, when using a device using such a magnetic card 11, the magnetic card 11 inserted into the card processing device 20 in the device is rotated in the same manner as described above, and during this rotation, the magnetic card 11 is rotated on the recording track 14. Each piece of data recorded on the magnetic head 22 is read out via the magnetic head 22.

The magnetic card 11 is continuously rotated in a fixed direction by the card processing device 20 until the card is returned.

Among the read data, the fixed data identifies whether or not this magnetic card 11 is legitimate, and the device can be used. When the use of the filter is completed, the read variable value γ- A value is subtracted from the value according to the frequency of use, and new variable binary data is obtained.

This new variable previous value data is stored in the rotating magnetic card 11.
The data is recorded in the variable area ta14a on the recording track 14 via the magnetic head 22, and after the rewriting of this data is completed, the data is read out again to confirm whether the data has been rewritten correctly.

If the rewritten data is correct, the turntable 21 stops rotating and the magnetic card 11 is returned. If the date change data is different, the magnetic card 11 is rewritten to the correct data, then the rotation of the magnetic card 11 is stopped and the card is returned.

As described above, data is read, rewritten, and confirmed 11 while the magnetic card 11 is rotating, and the device is used by the magnetic card 11.

<Other embodiments of the present invention> (Fig. 3(a), Fig. 3(b)
) J3. In the above embodiment, a magnetic card was explained as a recording card, but the present invention is not a magnetic card, but a magnetic card.
The same applies to devices that record and reproduce information using light or the like.

Further, in the above embodiment, a circular recording track was provided in the recording layer of the recording card, but this is different from the arc-shaped recording track 31 as shown in FIGS. 3(a) and 3(b). ．．
32 may be provided.

Further, in the above embodiment, the information on the recording card is rewritten and used, but the present invention is applicable to a recording card in which only fixed data is recorded without rewriting the information, such as a bank cash card. can be similarly applied.

<Effects of the Present Invention> As described above, in the recording card of the present invention, a recording track in which desired information is recorded in advance on a circle or an arc is formed on at least a portion of the flat rectangular substrate.

For this reason, the recording range of information is determined by the length of the circular recording track of the recording card, and compared to a recording card with the same external dimensions and a conventional straight recording track, the recording range of the information is determined by the length of the circular recording track. The recording track length becomes longer, and the information content 1 becomes larger accordingly. Furthermore, since information can be read, rewritten, and confirmed while the recording card and the reading and writing heads are rotated relative to each other in the same direction, the mechanism is simplified, and there is no need to reverse the recording card conveyance. The processing time for reading and writing can be shortened.
