BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic storage medium and a processing device for the same, and more particularly to an improvement in a magnetic data writing/reading device and a magnetic card.

In recent years, as computer information processing speeds up and the amount of information increases, magnetic card read/write devices have been used to write and read individual pieces of information onto magnetic cards.

According to this, the magnetic card is provided with only one magnetic storage area for storing magnetic data, and the alignment of the magnetic storage area and the magnetic head is performed by a step of the card transport system that transports the magnetic card. This is done indirectly by a predetermined step feed amount of the motor.

[0005] Therefore, when writing data to a location other than the designated location of the magnetic storage area that originally stores magnetic data, or when reading magnetic data from the designated location of the magnetic storage area, it is necessary to write data to a location other than the designated location of the magnetic storage area. Wrong data may be read from the Furthermore, to avoid this, the individual magnetic information storage addresses are spaced sufficiently apart. Therefore, the amount of information stored in the magnetic card is limited.

Therefore, without indirectly aligning the magnetic storage area and the magnetic writing/reading means, the magnetic storage area and the writing/reading means are directly aligned based on alignment data. Therefore, there is a need for a magnetic card, its processing device, and alignment method that can suppress erroneous magnetic data writing/reading processes as much as possible and can store high-density magnetic data.

[0007]

[Prior Art] FIGS. 8(a) and 8(b) are block diagrams of a conventional magnetic card read/write device.
) shows the cross-sectional view.

[0008] In Figure (a), the magnetic card read/write device has an upper case 3A and a lower case 3B provided in the device body 1 into which a magnetic card 4 is inserted. The upper case 3A is provided with a card recognition sensor 2A and a print position detection sensor 2B, and the lower case 3B is provided with a conveying belt 5, a magnetic head 6, a driving roller 7, and the like.

The functions of the device are as follows: First, when the magnetic card 4 is inserted into the device body 1, the card recognition sensor 2A
The insertion of the card 4 is recognized by this. As a result, the card 4 is moved by the drive roller 7 and the conveyance belt (hereinafter referred to as a card conveyance system) 5. At this time,
The alignment between the magnetic storage area A and the magnetic head 6 is performed by feeding the step motor in predetermined steps to change the distance from the end surface of the magnetic card 4 identified by the card recognition sensor 2A to the magnetic head 6. . Also,
An encoder is installed on the card transport rollers, gears, etc.
This is done indirectly by calculating the amount of movement of the magnetic card 4 from the rotation speed.

[0010] As a result, the write/read processing of magnetic data MD is performed at the specified position of the magnetic storage area A recognized by the control system.

[0011]

[Problems to be Solved by the Invention] However, according to the conventional example, as shown in FIG. The magnetic storage area A and the magnetic head (hereinafter also referred to as magnetic writing/reading means) 6 are aligned indirectly by a predetermined step feed amount of a step motor of a card transport system that transports the magnetic card 4. It is being carried out according to

[0012] Therefore, when writing data to a different position than the specified position of the magnetic storage area A that originally stores the magnetic data MD, or when reading the magnetic data MD from the specified position of the magnetic storage area A, , erroneous magnetic data MD may be read from another position. This is shown in Figure 8.
In (b), this is because a positional deviation α occurs between the actual movement amount of the magnetic card 4 and the movement amount of the control system (recognition unit), and the conveyance belt 5 and drive roller 7 of the magnetic card 4 are
It is thought that this is due to backlash in the gears of the card transport system such as the step motor, microslip in the belt, etc.

[0013] As a result, writing/reading of magnetic data MD cannot be performed at the specified position of the magnetic storage area A of the magnetic card 4 that is recognized by the control system, which reduces the reliability of the magnetic card read/write device. The first problem is that it leads to a decrease in performance.

In addition, in order to solve the first problem, in order to avoid erroneous writing/reading of magnetic data MD at the designated position of the magnetic storage area A designated by the control system, for each storage address of magnetic information, A method is adopted in which the storage locations are spaced sufficiently apart for writing processing.

[0015] As a result, compared to the magnetic storage capacity that can originally store magnetic information on the magnetic card,
There is a second problem in that the amount of written information is reduced because the storage location related to the storage address of the magnetic information is limited.

The present invention was created in view of the problems of the prior art, and it is possible to perform magnetic reading based on alignment data without indirectly aligning the magnetic storage area and the magnetic writing/reading means. By directly aligning the storage area and the writing/reading means, it is possible to suppress erroneous magnetic data writing/reading processes as much as possible and to store high-density magnetic data. The purpose is to provide a storage medium, its processing device, and alignment processing method.

[0017]

[Means for solving the problem] Figures 1(a) and (b) are
FIG. 2 is a principle diagram of a magnetic storage medium and a processing device thereof according to the present invention, and FIG. 2 shows a principle diagram of a magnetic storage medium alignment processing method according to the present invention.

The magnetic storage medium of the present invention, as shown in FIG.

A magnetic storage medium comprising:

Further, in the magnetic storage medium, the first magnetic storage area A1 and the second magnetic storage area A2 may be provided on the same surface or on different surfaces with respect to the card body 11, respectively. It is characterized by

Furthermore, in the magnetic storage medium, a storage address ADDi for storing the magnetic data MD in the first magnetic storage area A1 and a storage address for storing alignment dummy data DD in the second magnetic storage area A2 are provided. It is characterized by having certain rules between it and ADDj.

Further, as shown in FIG. 1(b), the magnetic storage medium processing apparatus of the present invention includes a moving means 12 for moving the magnetic storage medium 16, and a magnetic data M on the magnetic storage medium 16.
Magnetic writing/reading means 13 for writing/reading D
, a magnetic detection means 14 for detecting the alignment dummy data DD of the magnetic storage medium 16, and the moving means 12.
, a magnetic writing/reading means 13 and a control means 15 for controlling the input/output of the magnetic detection means 14, and the control means 15 controls the magnetic storage area A1 of the magnetic storage medium 16 based on the alignment dummy data DD. and the writing/reading means 13.

Note that the magnetic storage medium processing apparatus is characterized in that the magnetic storage medium 16 is the magnetic storage medium according to the present invention described above.

Furthermore, in the magnetic storage medium alignment processing method of the present invention, as shown in the flowchart of FIG. In step P1, the dummy data DD for positioning of the magnetic storage medium 16 is detected, and then, in step P2, writing/reading is performed in the magnetic storage area A1 of the magnetic storage medium 16 based on the dummy data DD for positioning. The above object is achieved by calculating the positional deviation ε with respect to the position p1, and then, in step P3, correcting the movement of the magnetic storage medium 16 based on the calculation process.

[0024]

[Function] According to the magnetic storage medium of the present invention, FIG.
), apart from the first magnetic storage area A1 of the card body 11, a second magnetic storage area A2 is provided in which alignment dummy data DD is stored.

For example, the first magnetic storage area A1 and the second magnetic storage area A2 are provided on the same surface with respect to the card body 11, and the first magnetic storage area A1 is a memory for storing magnetic data MD. A certain engagement rule is maintained between the address ADDi and the storage address ADDj that stores the positioning dummy data DD in the second magnetic storage area A2.

Therefore, when the second magnetic storage area A2 is detected from the end surface of the magnetic storage medium 16, the positioning dummy data DD in the second magnetic storage area A2 is detected.
is decoded. This makes it possible, for example, to compare and recognize the storage address ADDi of the first magnetic storage area A1 specified by the control system from the storage address ADDj of the second magnetic storage area A2.

[0027] As a result, the storage interval of individual magnetic information, which was conventionally adopted in order to avoid erroneous write/read processing of magnetic data MD at the specified position of the magnetic storage area A specified by the control system, can be changed. It becomes possible to relax restrictions. This allows high-density magnetic data to be stored in the originally writable magnetic storage area of the magnetic storage medium.
It becomes possible to store.

Further, according to the magnetic storage medium processing apparatus of the present invention, as shown in FIG. , the control means 15 corrects the position of the magnetic storage area A1 of the magnetic storage medium 16 and the magnetic writing/reading means 13 based on the positioning dummy data DD.

For example, when the magnetic storage medium 16 according to the present invention is inserted into the processing device, the magnetic storage medium 16 is moved by the moving means 12 via the control means 15. In addition, dummy data DD for positioning the magnetic storage medium 16
is a magnetic detection means 1 separate from the magnetic writing/reading means 13.
Detected by 4. At this time, the magnetic storage medium 16
When the second magnetic storage area A2 is detected from the end face of the second magnetic storage area A2, the alignment dummy data DD in the second magnetic storage area A2 is decoded. As a result, for example, the storage address ADDi of the first magnetic storage area A1 specified by the control system is immediately specified from the storage address ADDj of the second magnetic storage area A2, and the storage address ADDi of the first magnetic storage area A1 of the magnetic storage medium 16 is immediately specified. The moving means 12 is aligned with the magnetic writing/reading means 13.
It is possible to make corrections via

[0030] As a result, it is possible to perform writing and reading of magnetic data MD in the magnetic storage medium 16 with high accuracy and reproducibility at the designated position of the magnetic storage area A designated by the control system. becomes. This makes it possible to manufacture highly reliable magnetic card read/write devices and the like.

Furthermore, according to the magnetic storage medium alignment processing method of the present invention, as shown in the flowchart of FIG.
When performing write/read processing, step P
2, dummy data DD for positioning the magnetic storage medium 16
Based on the positional deviation ε between the magnetic storage area A1 of the magnetic storage medium 16 and the magnetic write/read position p1, for example, the storage address ADDj of the second magnetic storage area A2 and the first magnetic storage specified by the control system. The difference between the area A1 and the storage address ADDi is calculated.

Therefore, the positional deviation ε between the actual movement amount of the magnetic storage medium 16 and the movement amount of the control system (recognition unit) is as follows.
That is, the storage address ADDj of the second magnetic storage area A2
Since this is just a difference between the storage address ADDi of the first magnetic storage area A1 designated by the control system, backlash of the gears of the card transport system such as the belt for transporting the magnetic storage medium 16, the driving roller, and the step motor may occur. The influence of belt microslip etc. becomes almost irrelevant. With this, the magnetic storage area and the magnetic writing/reading means can be directly aligned based on the alignment data DD, without indirectly aligning the magnetic storage area and the magnetic writing/reading means as in the conventional example. It becomes possible to perform alignment. for example,
In step P3, the movement correction process of the magnetic storage medium 16 is performed based on the arithmetic processing, that is, at the storage address ADDj of the second magnetic storage area A2 corresponding to the storage address ADDi of the first magnetic storage area A1 specified by the control system. By moving, reading and checking the alignment dummy data DD, it becomes possible to accurately align the magnetic storage area A1 of the magnetic storage medium 16 and the magnetic write/read position p1.

As a result, unlike the conventional example, it is possible to write the magnetic data MD to a different position than the specified position of the magnetic storage area A that originally stores the magnetic data MD, or write the magnetic data MD from the specified position of the magnetic storage area A. When reading magnetic data MD, it is possible to suppress reading erroneous magnetic data MD from another position as much as possible. This makes it possible to improve the reliability of the magnetic information storage medium processing device, such as the magnetic card read/write device.

For example, the magnetic information area A1 and the distance information area A2 are provided on the same surface or on different surfaces of the magnetic card body 21, respectively. This is to avoid interference between the magnetic data MD and the alignment dummy data DD during write/read processing or storage management by the user. Also,

By providing an area for storing 1 to N distance information elements DLi, the detection resolution of the magnetic sensor is improved, and by providing an area for storing 1 to N distance information elements DLi in the horizontal direction, the magnetic information area This is to establish correspondence with the storage address ADDi of the magnetic data MD stored in A1.

For example, N=1 in the horizontal direction and M in the vertical direction.
A distance information element DL1 constituting a part of the positioning dummy data DD is stored in the storage area of =1, and is used for cue processing of the magnetic card 26, etc. Further, between the storage address ADDi that stores the magnetic data MD in the magnetic information area A1 and the storage address ADDj that stores the positioning dummy data DD in the distance information area A2, for example, a storage where the distance information element DL1 is stored is provided. Address ADD1 and storage address ADD1 in magnetic information area A1 storing magnetic data MD have a one-to-one relative relationship.

A distance information area A2 for storing alignment dummy data DD is provided on the same surface as the magnetic card main body 21, and alignment in the distance information area A2 with a storage address ADDi for storing magnetic data MD in the magnetic information area A1 is provided. There is a one-to-one relative relationship with the storage address ADDj that stores the dummy data DD.

Therefore, when the distance information area A2 is detected from the end surface of the magnetic card 26, the distance information area A2
The alignment dummy data DD in is decoded, and the distance information element DL1 is recognized. With this, for example,
It becomes possible to perform comparison recognition from the storage address ADD1 of the distance information area A2 with the storage address ADD1 of the magnetic information area A1 designated by the control system.

[0043] As a result, the storage interval of individual magnetic information, which was conventionally adopted in order to avoid erroneous writing/reading of magnetic data MD at the specified position of the magnetic storage area A specified by the control system, can be changed. It becomes possible to relax restrictions. This allows high-density magnetic data M to be stored in the originally writable magnetic storage area of the magnetic card 26.
It becomes possible to store D.

Next, the magnetic card 2 according to the embodiment of the present invention
A magnetic card read/write device using No. 6 will be explained below.

In FIG. 3A, the magnetic card read/write device for writing/reading magnetic data MD using the magnetic card 26 according to the embodiment of the present invention has an upper case 28A, an upper case 28A, and A lower case 28B is provided, and a card recognition sensor 2 is provided in the upper case 28A.
7A and a print position detection sensor 27B are provided, and the lower case 28B is provided with a conveyor belt 22A and a magnetic head 23.
, a driving roller 22B, a stepping motor 22C, a magnetic sensor array 24, and the like.

That is, the conveyor belt 22A constitutes a part of the moving means 12, and is used to move, for example, the magnetic card 26 according to the embodiment of the present invention. Further, the driving roller 22B constitutes another part of the moving means 12, and receives the rotational force of the step motor 22C to drive the conveying belt 22A. Note that the step motor 22C is driven to advance in predetermined steps via the motor control section 22D (see FIG. 7).

The magnetic head 23 is an embodiment of the magnetic write/read processing means 13, and is used to write/read the magnetic data MD of the magnetic card 26. In addition,
The magnetic data MD written/read by the magnetic head 23 is sent to the MPU 25 via the magnetic read/write section 23A.
(See Figure 7). Further, the distance between the mounting position of the magnetic head 23 and the mounting position of the card recognition sensor 27A that recognizes the end of the magnetic card 26 is defined as L1.

The magnetic sensor array 24 is the magnetic detection means 14
This is an example of detecting positioning dummy data DD in the distance information area A2 stored separately from the magnetic data MD of the magnetic card 26. Further, the positioning dummy data DD consists of distance information elements DLi stored in the distance information area A2, and is converted by the A/D converter 24A (see FIG. 7). Note that the magnetic sensor array 24 is provided separately from the magnetic head 23, and for example, both of them are connected to the magnetic information area A1 and the distance information area A2 of the magnetic card 26.
It is arranged in a straight line opposite the position where the and are lined up. Further, the magnetic sensor array 24 is made up of M magnetic detection elements arranged vertically (see FIG. 7).

MPU (microprocessor unit) 2
5 is an embodiment of the control means 15, which controls input and output of the magnetic head 23, the driving roller 22B, and the like. For example, the MPU 25 performs a process of correcting the write/read position p1 of the magnetic head 23 in the magnetic storage area A1 of the magnetic card 26 using the distance information element DLi based on the alignment dummy data DD.

In this way, according to the magnetic card read/write device according to the embodiment of the present invention, as shown in FIG. A detection sensor 27B is provided, and the lower case 28B includes a conveyor belt 22A, a magnetic head 23, a driving roller 22B, and a magnetic sensor array 2.
4, an MPU 25, etc., and the MPU 25 performs alignment correction processing between the magnetic storage area A1 of the magnetic card 26 and the magnetic head 23 based on alignment dummy data DD.

Therefore, when the magnetic card 26 according to the present invention is inserted into the processing device, the magnetic card 26
Drive roller 22B and conveyor belt 2 via U25
Moved by 2A. Further, dummy data DD for alignment of the magnetic card 26 is detected by a magnetic sensor array 24 separate from the magnetic head 23. At this time, the moving distance L1 from the end surface of the magnetic card 26 to the distance information area A2 is performed by a predetermined feeding process of a step motor or the like that drives the driving roller 22B, and the distance L1 is moved by the magnetic sensor array 24 in the distance information area A2. Distance information element DL1 is detected. Thereby, the alignment dummy data DD is decoded from the distance information element DL1 in the distance information area A2. With this, for example, the storage address AD of the distance information area A2
The storage address ADDj of the magnetic information area A1 specified by the control system is immediately specified from D1, and the alignment between the magnetic storage area A1 of the magnetic card 26 and the magnetic head 23 can be corrected for movement via the step motor. becomes.

[0053] As a result, it is possible to perform writing and reading of magnetic data MD of the magnetic card 26 with high precision and reproducibility at the designated position of the magnetic storage area A1 designated by the control system. Become. This makes it possible to manufacture highly reliable magnetic card read/write devices and the like.

Next, a magnetic card alignment method according to an embodiment of the present invention will be explained with supplementary explanation of the operation of the device.

FIGS. 5 and 6 are flowcharts (Part 1,
2), and FIG. 7 shows supplementary explanatory diagrams thereof.

For example, when performing write/read processing of magnetic data MD using the magnetic card 26 according to the embodiment of the present invention, the magnetic A case will be described in which the card 26 is aligned and then the magnetic data MD is written/read in steps P15 to P20.

That is, in the flowchart of FIG. 5, first, in step P1, it is confirmed whether or not the magnetic card 26 is inserted. At this time, if the magnetic card 26 is inserted (YES), the end face of the magnetic card 26 is recognized by the card recognition sensor 27A, so step P2
to move to. Further, if the magnetic card 26 is not inserted (NO), step P1 is continued.

Therefore, in step P2, motor starting processing is performed. At this time, the MPU 25, the motor control unit 22D
The step motor 22C is started via the step motor 22C.

[0059] Then, in step P3, the magnetic card 2
6 starts the L1 sending process. At this time, the magnetic head 2
Only the separation distance L1 between the mounting position of No. 3 and the mounting position of the card recognition sensor 27A that recognizes the end of the magnetic card 26 is performed as a predetermined feeding process of the step motor 22C.

Next, in step P4, the separation distance L2 from the card end face to the distance information area A2 is replaced with a predetermined number of steps n of the stepping motor. This extends from the card end surface of the magnetic card 26 to the magnetic information area A1,
It shows a process of moving a separation distance L2 to the distance information area A2.

Furthermore, in step P5, the magnetic card 2
The feeding process is performed by a predetermined number of steps n of 6. At this time, the step motor 22C is driven via the MPU 25 and the motor control unit 22D, and the magnetic card 26 is moved via the conveyance belt 22A and the drive roller 22B (
(See Figure 7).

Next, in step P6, the distance information element DL
1 is detected or not. At this time, if the distance information element DL1 is detected (YES), the process moves to step P15 to specify the storage address of the magnetic data MD. Furthermore, if the distance information element DL1 is not detected (NO), the process moves to step P7. here,
When the distance information element DL1 approaches the distance information area A2, it is detected by the magnetic sensor array 24, and is outputted by the A/D converter 24A to the MPU 25 as alignment dummy data DD (see FIG. 7).

Therefore, in step P7, a down-count process is performed in which the predetermined number of steps of the stepping motor 22C is set to n-1 and the predetermined number of steps n is sequentially decreased. This corresponds to the movement process until the magnetic information area A1 and distance information area A2 of the magnetic card 26 exceed the magnetic head 23. That is, this corresponds to a movement process in which the separation distance L2 from the card end surface of the magnetic card 26 to the magnetic information area A1 and the distance information area A2 is shortened to "0". At this time, if the magnetic information area A1 and the distance information area A2 exceed the magnetic head 23, the write/read positions of the magnetic storage area A1 of the magnetic card 26 and the magnetic head 23 are determined based on the positioning dummy data DD. Positional deviation ε from p1
is processed by the MPU 25.

Thereafter, in step P8, a predetermined number of steps n
A judgment process is performed to determine whether or not the value becomes 0. At this time, if the predetermined number of steps n becomes "0" (YES), the process moves to step P9. Further, the predetermined number of steps n is “0”.
'' (NO), the process returns to step P5 and the magnetic card 26 is fed by a predetermined number of steps n.

Therefore, in step P8, the predetermined number of steps n
If it becomes "0" (YES), L3 sending processing of the magnetic card 26 is performed in step P9. This is the magnetic information area A1 and distance information area A of the magnetic card 26.
From the end of 2 to the storage start position of magnetic data MD and alignment dummy data DD (for example, write/read position p
1) shows the movement process of separation distance L3 up to 1).

Therefore, in step P10, the magnetic card 26 is fed by a predetermined number of steps n. At this time, the step motor 22C is driven via the MPU 25 and the motor control unit 22D, and the magnetic card 26 is moved via the conveyance belt 22A and drive roller 22B (see FIG. 7).

After that, in step P11, the distance information element D
Processing is performed to determine whether L1 has been detected. At this time, if the distance information element DL1 is detected (YES), the process moves to step P15 to specify the storage address of the magnetic data MD. Furthermore, if the distance information element DL1 is not detected (NO), the process moves to step P12.

Therefore, in step P12, a down-count process is performed in which the predetermined number of steps is n-1 and the predetermined number of steps n is sequentially decreased. This is similar to step P7, from the ends of the magnetic information area A1 and distance information area A2 of the magnetic card 26 to the storage start position (for example, write/read position p1) of the magnetic data MD and alignment dummy data DD. This corresponds to the movement process until the point is crossed. That is, the separation distance L3 from the ends of the magnetic information area A1 and distance information area A2 of the magnetic card 26 to the storage start position of the magnetic data MD and alignment dummy data DD is set to "0".
This corresponds to the movement process that is shortened to . At this time, the positional deviation ε between the magnetic storage area A1 of the magnetic card 26 and the write/read position p1 of the magnetic head 23 is calculated by the MPU 25 based on the alignment dummy data DD.

Thereafter, in step P13, it is determined whether the predetermined number of steps n=0. At this time, if the predetermined number of steps n becomes "0" (YES),
The process moves to step P14. Further, if the predetermined number of steps n does not become "0" (NO), the process returns to step P10 and continues the feeding process by the predetermined number of steps n of the magnetic card 26.

Therefore, when the predetermined number of steps n becomes "0" (YES), the process moves to the flowchart (part 2) according to the embodiment of the present invention, and in step P14, the magnetic information area of the magnetic card 26 is This applies when the end of A1 and distance information area A2 cannot be found, so a card error is displayed.

[0071] Thereafter, in step P21, card ejection processing is performed and the control is ended.

Returning to the flowchart (part 1) according to the embodiment of the present invention, when specifying the storage address in step P15, the actual movement amount of the magnetic card 26 and the control system (recognition unit) The positional deviation ε, that is, the difference between the storage address ADD1 of the distance information area A2 and the storage address ADD1 of the magnetic information area A1 specified by the control system is MP.
Based on the positional deviation ε, the step motor 22C is driven via the motor control unit 22D, and the magnetic card 26 is moved by the conveying belt 22A and the driving roller 22B (see FIG. 7).

[0073] Thereafter, the process moves to the flowchart (part 2) according to the embodiment of the present invention, and in step P16, a process for confirming whether or not information is to be written to the magnetic card 26 is performed. At this time, if information is to be written (YES), the process moves to step P17. Also, if you do not write information (
If NO), the process moves to step P19.

Therefore, in step P17, the magnetic data M
Performs write processing of D. At this time, the magnetic data MD is originally stored at the specified position of the magnetic storage area A1 specified by the control system, that is, at the storage address ADD1 of the magnetic information area A1.
is written.

Thereafter, in step P20, the magnetic data MD
Confirmation processing is performed to determine whether or not the writing process has ended. At this time, if information writing is to be ended (YES), the process moves to step P21, where card ejection processing is performed, and the control is ended. Further, if the information writing process is not completed (NO), step P17 is continued.

On the other hand, if information is not written to the magnetic card 26 at step P16 (NO), step P1
9, the information is read from the magnetic card 26.

After that, in step P18, the magnetic data MD
Confirmation processing is performed to determine whether or not the read processing has ended. At this time, if information reading is to be ended (YES), the process moves to step P21, where card ejection processing is performed, and the control is ended. Further, if the information reading process is not completed (NO), step P19 is continued.

In this manner, according to the magnetic card write/read processing method according to the embodiment of the present invention, as shown in the flowchart of FIG. In this case, the magnetic card 26 is aligned based on the alignment dummy data DD in steps P1 to P13.

That is, in steps P6 and P11, based on the positioning dummy data DD of the magnetic card 26, the positional deviation ε between the magnetic storage area A1 of the magnetic card 26 and the write/read position p1 of the magnetic head 23, for example, The difference between the storage address ADDj of the distance information area A2 and the storage address ADDi of the magnetic information area A1 specified by the control system is calculated.

Therefore, the positional deviation ε between the actual movement amount of the magnetic card 26 and the movement amount of the control system (recognition unit) is the difference between the storage address ADDj of the distance information area A2 and the magnetic field specified by the control system. Since it is only a difference from the storage address ADDi of the information area A1, the conveyance belt 22A of the magnetic card 26,
The effects of backlash of gears in the card conveyance system such as the drive roller 22B and step motor 22C, microslip of the belt, etc. are almost irrelevant. With this,
Instead of indirectly aligning the magnetic storage area and the magnetic head 23 as in the conventional example, the magnetic information area A1, the distance information area A2, and the magnetic head 23 are directly aligned based on the alignment data DD. It becomes possible to perform alignment. From this, in steps P15 to P20, the movement correction process of the magnetic card 26 is performed based on the arithmetic processing, that is,
Storage address ADDi of magnetic information area A1 specified by the control system
By moving to the storage address ADDj of the distance information area A2 corresponding to , reading out the alignment dummy data DD and performing a confirmation process, the magnetic storage area A1 of the magnetic card 26 and the magnetic write/read position p1 can be accurately determined. It becomes possible to perform alignment.

[0081] As a result, the magnetic data M
When writing magnetic data MD to a position other than the specified position of magnetic storage area A that stores D, or reading magnetic data MD from a specified position of magnetic storage area A, there is a possibility that an incorrect magnetic It becomes possible to suppress reading of data MD as much as possible. This makes it possible to improve the reliability of the magnetic information storage medium processing device, such as the magnetic card read/write device.

In the embodiment of the present invention, an example has been described in which the storage address ADDi of the magnetic information area A1 and the storage address ADDj of the distance information area A2 are in a one-to-one relationship. It is not necessary to have a relative relationship. In this case, by moving to a position designated by the control system and then performing predetermined step feeding processing based on alignment dummy data, it is possible to perform alignment processing in the same manner as in the embodiment of the present invention.

[0083]

As explained above, according to the magnetic storage medium of the present invention, the second magnetic storage area for storing dummy data for alignment, separate from the first magnetic storage area, is attached to the card body. They are provided on the same surface or on different surfaces, and a certain engagement rule is maintained between the storage address of the first magnetic storage area and the storage address of the second magnetic storage area.

Therefore, when the second magnetic storage area is detected from the end surface of the magnetic storage medium, the positioning dummy data in the second magnetic storage area is decoded. This makes it possible to compare and recognize the storage address of the first magnetic storage area specified by the control system from the storage address of the second magnetic storage area. This makes it possible to store high-density magnetic data in the originally writable magnetic storage permissible area of the magnetic storage medium.

Further, according to the magnetic storage medium processing apparatus of the present invention, the moving means, the magnetic writing/reading means, the magnetic detecting means, and the controlling means are provided, and the controlling means performs magnetic recording based on the positioning dummy data. The positions of the magnetic storage area of the storage medium and the magnetic writing/reading means are corrected.

Therefore, when the magnetic storage medium according to the present invention is moved by the moving means, the alignment dummy data is detected by magnetic detection means different from the magnetic writing/reading means. As a result, the storage address of the first magnetic storage area specified by the control system is immediately specified from the storage address of the second magnetic storage area, and the position of the magnetic storage area of the magnetic storage medium and the magnetic writing/reading means is It becomes possible to correct the alignment.

Furthermore, according to the magnetic storage medium alignment processing method of the present invention, when writing/reading magnetic data to/from a magnetic storage medium, the magnetic storage medium is aligned in advance based on dummy data for alignment of the magnetic storage medium. The positional deviation between the magnetic storage area of the magnetic storage medium and the magnetic write/read position is calculated.

For this reason, the positional deviation between the actual movement amount of the magnetic storage medium and the movement amount of the control system (recognition unit) is determined by the storage address of the second magnetic storage area and the first magnetic field specified by the control system. Since it is recognized as a difference from the storage address of the storage area, the effects of gear backlash, belt microslip, etc. in the card conveyance system of the magnetic storage medium are almost irrelevant. This makes it possible to directly align the magnetic storage area and the writing/reading means, and the second magnetic storage area corresponds to the storage address of the first magnetic storage area specified by the control system. By moving to the storage address of , reading out the alignment dummy data and performing a confirmation process, it becomes possible to accurately align the magnetic storage area of the magnetic storage medium and the magnetic writing/reading means.

[0089] This makes it possible to write and read magnetic data with high accuracy and reproducibility at the designated position of the magnetic storage area designated by the control system. This allows for highly reliable magnetic card reading/
It greatly contributes to the provision of light devices.
