Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to an information recording medium having a recording area for machine-readable information and visual information for image information.

Securities such as cards, credit cards, and certificates of deposit;
There are various types of recording media, such as train tickets, gate tickets, and parking lot tickets.These recording media have a striped magnetic recording layer affixed to one or both sides of the medium surface, or have a magnetic recording layer covering the entire surface of the medium. , the other surface is configured as a recording layer for visual information.

FIG. 1 shows an example of a cross-sectional view of these recording media.

Figure 1 shows one of the cross-sectional sizes of tickets currently in use. The recording medium 1 has a thickness of about 200 to 220 μm, and has a structure such that a base (paper) 20 has a thermosensitive recording layer 3 with a thickness of 10 to 15 μm on one side, and a magnetic recording layer 4 with a thickness of 10 to 15 μm on the other side. It is being The thickness of the base 2 is 180~190μ
It is m. In the case of a commuter pass, the thickness of the base 2 is also increased, and a transparent retention layer may be provided on the surfaces of the heat-sensitive recording layer 3 and the magnetic recording layer 4.

(3) Problems with the prior art The ninth problem is that printing cannot be done there, and the printing is finely compressed and printed on other surfaces, and sometimes even the printing spellings are omitted. On the other hand, a method of directly printing onto the magnetic recording layer4 has been proposed, but since the method and material for printing the printed matter onto the magnetic recording layer have not been established, conventional methods do not allow printing/printing during use. There is a problem with the turn being taken away.

(4) Purpose of the present invention The present invention has been developed to improve the above-mentioned situation, and it enables the information to be written on the face of the ticket to be printed on both sides of the recording medium without fail, and also enables the information to be read by a machine. The purpose is to provide a structured information recording medium.

(5) Summary of the Invention In order to achieve the above object, the present invention provides a heat-sensitive recording layer on both sides of which a visual pattern is recorded, and a magnetic recording layer is provided in the western part of the recording medium.

(6) Description of Embodiment An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

FIG. 2 is a cross-sectional view of an information recording medium showing an embodiment of the present invention, and the thickness of the recording medium 11 is approximately the same as that of the conventional one shown in FIG. The recording medium 11 has a thickness of 160 to 180 mm.
．． A thermosensitive recording layer 13 with a thickness of 10 to 15 μm on one side of the base 120 of the SM, and a magnetic recording layer 14 with a thickness of 10 to 15 μm on the other side.
is provided with a thickness of 1 on the surface of the magnetic recording layer 14.
A heat-sensitive recording layer 15 with a thickness of 0 to 15xm is provided. Base 12
The thickness of the recording medium 11 is shown to be thinner than the conventional one in order to conform to the conventional standard.

Next, a method for recording information on this information recording medium 11 and a method for reading the information will be explained. This information recording medium 11 is often used for train tickets, commuter passes, tickets, etc., for example, railways.

Taking a train ticket as an example of one of the above-mentioned information recording media, ticket information such as departure station, section, fare, date of issue, etc. is printed on the heat-sensitive recording layer 13 side, and precautions regarding the ticket are printed on the power recording layer 15. Matters, contract matters, etc. are described. The ticket issuing device records visual information on the heat-sensitive recording layer 11.15 of the ticket paper (recording medium 11), and then inputs information such as departure station, number of wards, date of issue, etc., and sometimes a code, etc., in machine language to the magnetic recording layer 14. do. In this case, magnetic recording is performed from the top of the thermosensitive recording layer 15 in the case of horizontal recording. The ticket that has been magnetically recorded is released from the ticket issuing device and delivered to the user. The user inserts this ticket into the automatic ticket gate. The automatic ticket gate machine uses the magnetic recording layer 1 of the inserted ticket.
Regarding the configuration of the magnetic head of an automatic ticket gate device, which reads and judges the information described in 4, and checks the ticket of the user, as already described in Japanese Patent Publication No. 49-1240, etc. , so that it can be read regardless of whether the roll is conveyed from the front or the back. The recording medium of the present invention can also use this device.

Of course, the read second signal is smaller than that of the conventional recording medium shown in FIG. However, in recent years, magnetic recording technology and reading technology have improved, and for example, it has become possible to read the information on the magnetic recording layer 4 of the ticket shown in FIG. 1 from the heat-sensitive recording layer 3111 without any problem. . Of course, the signal will be smaller, but it will not affect the reading itself, and since both sides are thermal recording, there is less chance that the visual pattern will be scratched off during use and become illegible compared to electrostatic printing.
Furthermore, the number of wearable parts in the ticket issuing device is also reduced.

Further, FIG. 3 shows another embodiment of the present invention. In this method, a magnetic recording layer 22 with a thickness of 10 to 15 μm is provided at the center of the information recording medium 21, a base 23, 24- with a thickness of 80 to 90 μm is attached to both sides of the magnetic recording layer 22, and a base 23, 24- with a thickness of 10 to 15 μm is attached to the outer surface.
25.26 heat-sensitive recording layers with a thickness of 15++ m were provided. The thickness of the recording medium 21 is the same as the conventional one.

This is a rounding that does not change the conventional standard, and if the conventional standard itself is revised, the thickness of the recording medium can be changed freely. Then, the recording medium 21 in FIG.
According to
[K can also be recorded arbitrarily. Furthermore, since the magnetic recording layer 22 is located at the center of the recording medium, magnetic information is transferred to the thermosensitive recording layer 25.
Equal strength signals are obtained when read from either side of 26. Therefore, unlike conventional automatic ticket gates, there is no need to provide separate magnetic heads for the front and back, and it is sufficient to have only one of the magnetic heads.

Further, unlike ID card readers in financial institutions, it is no longer necessary to specify the insertion direction JK (front and back) of the card before inserting the card.

(7) As described in detail about the present invention, according to the present invention, not only can visually visible information be recorded on both sides of a recording medium, but also information can be read by a machine as in the past. It has the following characteristics. Moreover, since the visual information is thermally recorded, there is less risk that the pattern on the card surface will be scratched off and become difficult to see compared to electrostatic or ink systems.
