Description

  The present invention relates to a magnetic recording medium processing apparatus and a magnetic recording medium processing method for writing magnetic information with a write current value suitable for the coercive force of the magnetic recording medium, and has a function of avoiding a transaction interruption due to a magnetic information writing error. The present invention relates to a magnetic recording medium processing apparatus and a magnetic recording medium processing method.

  Magnetic recording media such as magnetic cards have been standardized so that the coercive force of the magnetic recording portion such as the magnetic stripe differs. For example, in addition to the low coercive force card (for example, 300 to 400 Oe) that has been standardized conventionally, a high coercive force card (for example, 2750 Oe) has been newly standardized. From the viewpoint of protecting magnetic data recorded on the magnetic card, the use of a high coercive force card is advantageous, but a low coercive force card is also widely used, and a high coercive force card and a low coercive force card are mixed. in use.

  In the magnetic card reader, there is no problem when reading the magnetic information of the magnetic card, but when writing the magnetic information to the magnetic stripe, it is necessary to write with a write current value suitable for the coercive force of the magnetic card. For this reason, when writing with a write current value suitable for a low coercive force card with respect to a high coercive force magnetic card, the magnetic information of the magnetic card is not rewritten because the write current is too small. Magnetic information will remain. In addition, if writing is performed at a write current value suitable for a high coercive force card with respect to a low coercive force magnetic card, the write current may be too large, and a pseudo peak may be generated. May become abnormal.

  In an apparatus that handles magnetic media having different coercive forces, the coercive force information relating to the magnetic coercive force of the magnetic medium written in advance in a predetermined area of the magnetic medium is read, the read coercive force information is determined, and the predetermined coercive force information is determined according to the determination result. A magnetic medium handling apparatus is known in which magnetic information is written on a magnetic medium at a current value of 1 and the magnetic information is written at a current value suitable for the coercive force of the magnetic medium (for example, Patent Documents). 1).

  Also, in a device that handles magnetic media with different coercive forces, it reproduces the magnetic information of the magnetic media inserted from the card insertion slot, and writes it with a recording current value for high coercive force when no magnetic information is recorded. Next, after erasing the magnetic information with a current value that can erase only the magnetic information of the low coercive force medium (DC erasing), the magnetic information of the magnetic medium is reproduced, and the number of remaining output peaks exceeding a certain output value There is also known a magnetic medium handling device that determines whether the magnetic medium is a high coercive force medium or a low coercive force medium based on the number of remaining output peaks (see, for example, Patent Document 2).

  However, in the magnetic medium handling apparatus described in Patent Document 1 and Patent Document 2, when a magnetic error is written by writing a magnetic information with a current value suitable for the coercive force of the magnetic medium, the same current value is used again. In some cases, writing errors cannot be avoided due to writing. For example, if a writing error such as a bankbook or a card cannot be avoided, the magnetic medium handling device determines that the magnetic recording medium cannot be used normally, returns the magnetic recording medium to the medium user, and handles the transaction. Was interrupted. For this reason, the media user not only can not complete the transaction that has been done, but also tells the window that the magnetic recording medium cannot be used normally, and reissues the magnetic recording medium such as a passbook or card. There was a problem that it could not be traded until it was done.

  In addition, even when a variety of standard magnetic cards are used together, in the case of a conventional card reader, when a write error occurs, the transaction is interrupted in order to write again at the same current value. There was a problem.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a magnetic recording medium processing apparatus and a magnetic recording medium that can avoid a transaction interruption due to an error in writing magnetic information to the magnetic recording medium. It is to provide a medium processing method.

Rewriting means for rewriting the magnetic information on the magnetic recording medium with a built-in current value.

  According to the present invention, when the medium evaluation unit determines that the magnetic recording medium on which the magnetic information is written with the first write current value corresponding to the coercive force of the magnetic recording medium is normally unusable, the rewriting is performed. Since the means rewrites the magnetic information on the magnetic recording medium with the second write current value that is larger than the first write current value, the magnetism in which the magnetic information is written with the appropriate first write current value Even if it is determined that the recording medium cannot be used normally, the level (base) of the output value of the magnetic information to be written is increased to make it a readable output value, thereby preventing the transaction from being interrupted. And complete the transaction to the end.

  That is, the magnetic recording medium processing apparatus according to the present invention can avoid a writing error due to an insufficient output value of magnetic information even if there is a magnetic information writing error during the transaction, and complete the transaction. Temporary relief (avoid transaction interruption). Therefore, the medium user can perform procedures such as reissuance of cards after necessary transactions, and convenience is improved.

  Note that the reason why a readable output value cannot be obtained despite writing with an appropriate first write current value is that the magnetic recording medium and the magnetic head are not bent due to bending or deformation of the magnetic recording medium. When the space becomes wide (such as a card that needs to be replaced or reissued), or when the contact position or contact angle between the magnetic recording medium and the magnetic head is not normal (variation), the output value of the written magnetic information is By becoming insufficient.

In addition to reducing the number of situations where the magnetic recording medium cannot be traded, if the magnetic recording medium becomes untradeable, the medium user can be informed that the magnetic recording medium cannot be traded.

  (3) When the writing determination unit determines that the writing result of the magnetic information by the first writing current value is not normal, the writing determination unit uses the first writing current value for the magnetic recording medium. When the writing of the magnetic information is repeatedly performed and the writing result of the magnetic information is not determined to be normal while the writing is repeated a predetermined number of times, the medium evaluation unit determines that the magnetic recording medium is not normally usable. A magnetic recording medium processing apparatus.

  According to the present invention, it is possible to avoid a write error due to a mere medium misalignment or the like by retrying with the first write current value corresponding to the coercive force of the magnetic recording medium.

  (4) The rewrite unit may set the rewrite unit to have a value greater than the first write current value when the write determination unit determines that the magnetic information write result based on the second write current value is not normal. The magnetic information is written to the magnetic recording medium with a large third write current value, and the medium evaluation unit is configured to cause the write determination unit to write the magnetic information according to the third write current value. If the magnetic recording medium is not determined to be normal, it is determined that the magnetic recording medium cannot be traded.

  According to the present invention, even when the write determination means determines that the magnetic information write result by the second write current value is not normal, the magnetic information is further written by the third write current value. When the result of writing magnetic information by the write current value is normal, the transaction can be prevented from being interrupted as a write error, and the transaction can be completed to the end.

  (5) The magnetic recording medium processing device, wherein the third write current value is equal to or higher than the second write current value.

  According to the present invention, since the third write current value is the same value or higher than the second write current value, the level (base) of the output value of the magnetic information to be written is increased and read. Possible output values.

  (6) The first write current value is a current value corresponding to a magnetic recording medium for low coercive force, and the second write current value is a current value corresponding to a magnetic recording medium for high coercive force. A magnetic recording medium processing apparatus, wherein:

  According to the present invention, when magnetic information is written to a magnetic recording medium for low coercive force at a current value corresponding to the magnetic recording medium for low coercive force, the magnetic recording is caused by an insufficient output value of the magnetic information. Even if it is determined that the medium cannot be used normally, writing is performed again with a large power current value corresponding to the magnetic recording medium for high coercive force, so the level of the output value of the magnetic information to be written (base ) Can be appropriately increased to a readable output value.

  (7) Magnetic recording medium processing comprising coercive force determination means for determining a coercive force of the magnetic recording medium and setting a write current value corresponding to the coercive force as the first write current value apparatus.

  According to the present invention, since the coercive force of the magnetic recording medium is determined and the write current value corresponding to the coercive force is set as the first write current value, the first most suitable for the coercive force of the magnetic recording medium. Magnetic information can be written to the magnetic recording medium using the write current value of.

Since the process rewrites the magnetic information to the magnetic recording medium with the second write current value that is larger than the first write current value, the magnetic information in which the magnetic information has been written with the appropriate first write current value Even if it is determined that the recording medium cannot be used normally, the level (base) of the output value of the magnetic information to be written is increased to make it a readable output value, thereby preventing the transaction from being interrupted. And complete the transaction to the end.

  That is, the magnetic recording medium processing method according to the present invention can avoid at least a writing error due to an insufficient output value of magnetic information even if there is a magnetic information writing error during the transaction, and complete the transaction. Temporary relief (avoid transaction interruption). Therefore, the medium user can perform procedures such as reissuance of cards after necessary transactions, and convenience is improved.

  (9) In the medium evaluation step, when the writing result of the magnetic information rewritten in the rewriting step is normal, a warning that the magnetic recording medium should be updated is transmitted, while the rewriting A magnetic recording medium processing method comprising: a warning sending step of sending a warning indicating that transaction is impossible when the result of writing the magnetic information rewritten in the loading step is not normal.

  According to the present invention, when the writing result of the magnetic information rewritten in the rewriting process is normal, the transaction can be completed to the end, while the warning sending process should update the magnetic recording medium. Since the warning is transmitted, it is possible to notify the medium user that the magnetic recording medium needs to be updated, and it is possible to prevent the magnetic recording medium from becoming inoperable in advance.

  In the magnetic recording medium processing method according to the present invention, when the writing result of the magnetic information rewritten in the rewriting process is not normal, the warning sending process sends a transaction impossible warning. In addition to reducing the number of situations where the magnetic recording medium cannot be traded, if the magnetic recording medium becomes untradeable, the medium user can be informed that the magnetic recording medium cannot be traded.

It is a flowchart which shows 3rd Embodiment of the magnetic recording medium processing method which concerns on embodiment of this invention. It is a figure which shows the saturation characteristic of each coercive force card | curd.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The medium evaluation means for determining whether or not the magnetic recording medium can be normally used is a method of reading magnetic information despite the fact that writing was performed with the first write current value suitable for the coercive force of the magnetic recording medium. When it is not written with a possible output value, it is determined that it cannot be used normally.

Specifically, the reason why a readable output value cannot be obtained even though the magnetic recording medium is written with an appropriate first write current value is as follows:
(1) The space between the magnetic recording medium and the magnetic head is widened by bending or deformation of the magnetic recording medium (in the case of a card that requires replacement or reissue).
(2) When the contact position or contact angle between the magnetic recording medium and the magnetic head is not normal (variation)
(3) The output value of the written magnetic information is insufficient due to the use of a magnetic card of a different standard.

  In this magnetic recording medium processing apparatus, an appropriate write current is a current value corresponding to the coercive force of the magnetic recording medium. Further, the coercive force of the magnetic recording medium is set based on the standards shown in Table 1.

  No. in Table 1 Writing magnetic information with a low coercive current value or a high coercive current value based on the coercive force defined by international standards a and b is mainly applied to credit card backside stripes and passbook stripes. . In addition, No. 1 was standardized as an international standard around 2008. c is the writing of magnetic information by an intermediate coercive force (650 Oe), and is used for a hotel key card.

  On the other hand, the international standard No. Japanese standards corresponding to a and b are No. d (JISX6302-2), No. e (JISX6302-6). In Japan, the standard for using an intermediate coercive force (650 Oe) for a cash card surface stripe is No. f (JISX6301).

  This magnetic recording medium processing apparatus is used not only when an appropriate write current is selected but also when an appropriate write current is not selected in a situation where magnetic cards of various standards are used together. By executing the writing again with the second writing current value larger than the first writing current value, it is possible to avoid interruption of the transaction.

The CPU 1 controls the operation of the magnetic card reader 10 via the magnetic R / W-IC 2 and a document for determining whether or not the writing result of the magnetic information written on the magnetic recording medium 20 is normal. And a medium evaluation unit 13 for determining whether or not the magnetic recording medium 20 can be normally used based on the determination of the write determination unit 12.

  The magnetic card reader 10 of this embodiment corresponds to, for example, a 300 Oe low coercive force card and a 2750 Oe high coercive force card. The magnetic head 4 is for a 2750 Oe high coercive force card, for example, and can be used for a 300 Oe low coercive force card by changing the magnitude of the current. The recording current circuit 3 can also be configured to supply a write current having a current value of 3 or more to the recording head 5, and is suitable for writing to the magnetic recording medium 20 from a write current having a current value of 2 or more. The first write current value can be selected.

  FIG. 5 shows the saturation characteristics of each coercive force card. The saturation current of the low coercive force card (300 Oe) is 12.5 mA 0-p (zero-peak). The write current is generally about 1.5 to 3 times the saturation current value in consideration of the margin of the write capability of the magnetic head 4 and the like.

  The writing determination unit 12 reproduces the magnetic information written on the magnetic recording medium 20 with the reproducing head 6 and determines whether or not the writing result of the magnetic information written on the magnetic recording medium 20 is normal. When the writing result of the magnetic information written in the magnetic recording medium 20 with the high coercive force current value is normal, the medium evaluation unit 13 issues a warning that the magnetic recording medium 20 should be updated and writes the information. The process ends (S308). This magnetic card reader 10 avoids interruption of transactions due to a write error by writing again with a high coercive current value with a strong writing force even if a write error occurs with a low coercive current value. be able to.

  On the other hand, when the writing result of the magnetic information written in the magnetic recording medium 20 with the high coercive force current value is abnormal, the medium evaluation unit 13 gives a warning that the transaction of the magnetic recording medium 20 is impossible. The transmission is made and the writing is terminated (S308).

  If it is determined in step S302 that the magnetic recording medium 20 is a high coercive force card, the control unit 11 sets a high coercive force current value as the first write current value, and sets the magnetic recording medium 20 in the magnetic recording medium 20. Writing of magnetic information is executed (S309, S310).

  The writing determination unit 12 reproduces the magnetic information written on the magnetic recording medium 20 with the reproducing head 6 and determines whether or not the writing result of the magnetic information written on the magnetic recording medium 20 is normal. When the writing result of the magnetic information written on the magnetic recording medium 20 is normal, the medium evaluation unit 13 determines that the magnetic recording medium 20 can be normally used and ends the writing (S311).

  On the other hand, when the writing result of the magnetic information written on the magnetic recording medium 20 is abnormal, the medium evaluation unit 13 determines that the magnetic recording medium 20 cannot be normally used (S311). In the case of the present embodiment, the magnetic card reader 10 cannot set a write current value larger than the high coercive force current value, and thus ends the writing.

  If the magnetic card reader 10 can set a write current value larger than the high coercive force current value, the second write current value may be set and the writing may be executed again. If the magnetic card reader 10 also supports intermediate coercive force, the intermediate coercive current value may be set as the second write current value for the low coercive force current value.

[Main effects of the present embodiment]
Even if there is a magnetic information write error during transaction, the present invention completes the transaction by increasing the write current value and rewriting the magnetic information, thereby causing a magnetic information write error. Transaction interruptions can be avoided. Therefore, the medium user can perform procedures such as reissuance of cards after necessary transactions, and convenience is improved.
