Transfer to the host device. When the first magnetic head 1 sends the data for one track read and reproduced from the magnetic stripe 17 of the passbook 16, the host device converts the data into data for three tracks (ST3). The converted data is returned to the microprocessor 41 via the driver receiver 44.

The microprocessor 41 sends the returned data to the RAM 43 as a signal 6 for temporary storage, and then reads the data for the three tracks from the RAM 43 and records the recording portions 2b, 2 of the second magnetic head 2.
Data is recorded on the magnetic stripe 19 of the passbook 18 by d and 2f (ST4). On the other hand, when it is determined in S1 that the conversion from the first magnetic head 1 to the second magnetic head 2 is not performed,
The microprocessor 41 determines whether or not the instruction content is a conversion from the second magnetic head 2 to the first magnetic head 1 (ST5).

In the case of conversion from the second magnetic head 2 to the first magnetic head 1, the reproducing unit 2a of the second magnetic head 1,
The data of the magnetic stripe 19 of the passbook 18 is read by 2c and 2e (ST6), reproduced, and transferred to the host device. In the host device, the second magnetic head 2 reads from the magnetic stripe 19 of the passbook 18 and reproduces it.
When the data for the track is sent, this data is set to 1
The data is converted into track data (ST7), and the converted data is returned to the microprocessor 41 via the driver receiver 44.

The microprocessor 41 sends the returned data to the RAM 43 as a signal 6 for temporary storage, then reads the data for one track from the RAM 43, and the recording unit 1b of the first magnetic head 1 passes the passbook. Data is recorded on 16 magnetic stripes 17 (ST8).
When it is determined that the conversion from the second magnetic head 2 to the first magnetic head 1 is not performed in ST4, the process according to the instruction content is executed and the process ends.

Such processing is effective, for example, when the number of recording tracks on the magnetic stripe of a passbook or a card is switched from the old specification to the new specification and issuance. In addition, the data read by the first magnetic head 1 is converted into the data of the second magnetic head 2, or
In order to cause any one of the host device 81, which is the bookkeeping machine control unit 84, the control device 85, or the host computer 81 to give an instruction to convert the data read by the magnetic head 2 into the data of the first magnetic head 1, The program of the magnetic stripe data processing device 83 can be easily executed without changing.

The above-described first embodiment is an example in which the first magnetic head 1 is used for one track and the second magnetic head 2 is used for three tracks. Alternatively, any combination of two-track and three-track is possible, and the same action and effect can be expected. Next, a second embodiment will be described.

FIG. 11 is a block diagram showing a second embodiment of the magnetic stripe data processing device according to the present invention. In this embodiment, the second magnetic head 2 is provided with a pair of reproducing units 1a.
And a recording unit 1b, and controls the reproduction control circuit 21, the recording control circuit 22, the reproduction control circuit 23, and the recording control circuit 24 so as to correspond to data having a recording density or recording format different from that of the first magnetic head 1. The contents are set.

The operation of the second embodiment will be described. For example, the first magnetic head 1 and the second magnetic head 2
When performing recording with different recording densities, different count values are set in the respective counters 62 so that the outputs of the recording control circuit 22 and the recording control circuit 24 are different. FIG. 12 is a diagram showing the recording timing of the first magnetic head 1 and the second magnetic head 2 in this embodiment.
By making the count value of the counter 62 of the recording control circuit 24 different from the count value of the counter 62 of the recording control circuit 24, the signal S2 input from the photo encoder 6 to each counter 62 is changed.
Thus, the timing signals of S62a (control circuit 22) and S62b (control circuit 24) can be generated from the respective counters 62.

In this case, the period of the input signal S2 is T,
When the cycle of the timing signal S62a is 2T and the cycle of the timing signal S62b is 4T, the interval of the magnetic flux reversal line A by the timing signal S62a is L and the interval of the magnetic flux reversal line b by the timing signal S62b is 2L, which are different. It can correspond to the recording density. As a result, data can be recorded at different recording densities by the magnetic head 1 and the magnetic head 2 on the tracks 17a of the same type of magnetic stripe, for example, the magnetic stripe 17 of the passbook 16 shown in FIG.

Further, when reproducing data having different recording densities, it is possible to easily cope with this by changing the circuits of the decoders 54 of the reproduction control circuit 21 and the reproduction control circuit 23. Therefore, according to this, data is reproduced with different magnetic characteristics by the first magnetic head 1 and the second magnetic head 2 on the same type of magnetic stripe, for example, the track 17a of the magnetic stripe 17 of the passbook 16 shown in FIG. Since it can be recorded, for example, when a customer of one bank transacts with an automatic transaction device at another bank, or by changing the recording density of the passbook or the magnetic stripe of the card at the same bank, When processing data on a magnetic stripe for each of a passbook or card that has a magnetic stripe and a passbook or card that has a changed magnetic stripe, or when a bank or the like has a passbook or a card that has magnetic stripes of multiple types of specifications. It is also possible to operate when mixed media such as cards are used.

Next, reproduction and recording of data when magnetic characteristics such as coercive force and residual magnetic flux on the magnetic stripe are different will be described. For example, when the residual magnetic flux of the magnetic stripe is different, the output current of the magnetic head during reproduction generally changes, so the amplification factor of the reproduction amplifier needs to be changed.
In this embodiment, by changing the values of the registers 55 of the reproduction control circuit 21 and the reproduction control circuit 23, the amplification factors of the amplifiers 52 of the reproduction amplifiers 31 and 33 can be changed independently.

As a result, the first magnetic head 1 and the second magnetic head 1
The magnetic head 2 can read and reproduce the data with respect to the magnetic stripes having different residual magnetic fluxes by the reproducing units 1a and 2a. In addition, when the coercive force of the magnetic stripes is different, it is generally necessary to change the value of the current passed through the magnetic head during recording.

In this embodiment, by changing the value of the register 63 of each of the recording control circuit 22 and the recording control circuit 24, the values are supplied to the recording portions 1b and 2b of the first magnetic head 1 and the second magnetic head 2. The current can be changed independently. As a result, recording can be performed on magnetic stripes having different coercive forces between the first magnetic head 1 and the second magnetic head 2.

Therefore, according to this, data can be reproduced and recorded on the magnetic stripes having different magnetic characteristics, so that, for example, a customer of one bank makes a transaction at another bank with an automatic transaction device. In some cases, at the same bank,
By changing the magnetic characteristics of the magnetic stripe of the passbook or card, the data processing of the magnetic stripe is performed for each of the passbook or card having the magnetic stripe before the change and the passbook or card having the magnetic stripe after the change. It is also possible to deal with cases such as when a bank or the like operates a mixture of media such as passbooks and cards having magnetic stripes of multiple types of specifications.

Next, reproduction and recording of data when the data recording mode of the magnetic stripe is different will be described. 13A and 13B are diagrams showing examples of different data recording formats. As shown in this figure, in the data recording mode of FIG. 13A, the character structure is 4 bits + 1 parity bit, and the starting code is 1 character, the data code is m character, the ending code is 1 character, and the LRC code is 1 character. .

The data recording format of FIG. 13 (b) is
The character configuration is 4 bits, and the starting code is 1 character, the data code is n characters, the ending code is 1 character, and the CRC code is 8 bits. When there is a passbook or a card having a magnetic stripe with a different data recording mode, for example, the first magnetic head 1, the reproduction amplifier 31, the reproduction control circuit 21, the recording amplifier 32, and the recording control circuit 22 shown in FIG. The second magnetic head 2 and the reproducing amplifier 3 are set so as to correspond to the data recording mode of (a).
3, the reproduction control circuit 23, the recording amplifier 34, and the recording control circuit 24 are set so as to correspond to the data recording mode of FIG. 13B, no matter which data recording mode, Recording and reproduction can be performed.

Therefore, according to this, for example, when a customer of one bank makes a transaction at another bank with an automatic transaction device, or when the same bank changes the data recording format of a passbook or a magnetic stripe of a card. This allows you to process magnetic stripe data for a passbook or card that has the magnetic stripe before the change and for a passbook or card that has the magnetic stripe after the change, or if you use a magnetic stripe with multiple types of specifications at banks, etc. It is also possible to handle a case where a medium such as a passbook or a card that is held is mixed and operated.

In addition to this, according to the second embodiment having the above-mentioned structure, it is possible to perform the same operation as that of the first embodiment. For example, as explained in FIG.
The data read and reproduced by the first magnetic head 1 and the data read and reproduced by the second magnetic head 2 are determined to automatically recognize the specifications of the magnetic stripe, and the magnetic data corresponding to the recognized magnetic stripe is determined. Data is recorded by the head, and as described with reference to FIG. 10, the data read and reproduced by the first magnetic head 1 or the second magnetic head 2 is reproduced by the second magnetic head 2 or the first magnetic head 2. It is also possible to convert the data into data corresponding to the head 1 for recording.

Further, in the above-mentioned embodiment, both the first magnetic head 1 and the second magnetic head 2 correspond to one recording track, but a plurality of same number of recording tracks are supported. Also, the same action and effect can be obtained.
Further, although the above-described first and second embodiments have been described by taking a bankbook of a financial institution as an example of a medium provided with a magnetic stripe, a cash card, a boarding pass of an aircraft in the passenger field, or a boarding of a train. Even when data is recorded on a magnetic stripe provided on a ticket or the like, or when the recorded data is read and reproduced, the same operation and effect can be obtained.
