Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a magnetic card having a magnetic recording layer on its surface.

<Prior art> When it is desired to add visual information such as other characters or marks to a magnetic card such as a cash card without changing the design of the portion other than the magnetic recording layer on the surface of the card. In recent years, information has been formed on the surface of the magnetic layer by screen printing. There is also a magnetic recording medium that records visual information such as characters by partially removing a colored layer formed on a magnetic layer, as disclosed in Japanese Utility Model Application Laid-open No. 52-132807. As disclosed in the publication, there is a magnetic recording medium consisting of a carrier and a magnetic film, in which a regular uneven pattern is provided on the front or back surface of the magnetic film.

<Problem to be solved by the invention> However, in screen printing, the magnetic layer of the printed part is eroded due to the use of containers, and the durability of that part deteriorates significantly. As the card is used more frequently, the magnetic layer on the printed part peels off from the card body due to friction with the head of the reader, gradually spreading to the surrounding area, and eventually being destroyed to the point where it no longer functions. become.

Moreover, in order to improve the suitability for screen printing and to make the ink layer as thin as possible, printing onto magnetic layers tends to include a larger amount of solvent in the ink than standard, which eliminates the above drawbacks. The result is that it helps.

Furthermore, when a colored layer is provided on the magnetic layer, the same effect may be exerted on the magnetic layer due to the solvent contained in the colored layer.

Furthermore, when a pattern of visual information such as letters or marks is provided in the magnetic recording portion of the magnetic layer, the pattern itself becomes large in order to be clearly distinguished, which poses a problem in reading the magnetic recording.

Therefore, the purpose of this invention is to create a magnetic card that can prevent the above-mentioned damage when forming patterns on the magnetic layer, and can also form patterns as clear as printing methods. The purpose of the present invention is to provide a pattern in which the non-recording portion of the magnetic layer is cut in the shape of a character to form those patterns in the magnetic layer.

<Means for Solving the Problems> The present invention, which has been made to achieve the above object, provides a magnetic card in which the non-recording portion of the magnetic layer is formed in the shape of characters, thereby forming those patterns on the magnetic layer. It is.

<Function> As described above, according to the present invention, the magnetic layer is not formed in the shape of the characters to form those patterns that are visual information, so the durability against friction of the magnetic layer is improved and magnetic recording and reproduction are improved. A clear pattern can be formed without any interference.

<Example> Hereinafter, the present invention will be described in detail based on an example of the drawings.

As shown in FIG. 1, on the surface of the magnetic card 1 of the present invention, a magnetic layer 2 is formed, for example, in the form of stripes. In this magnetic layer 2, a character pattern 3 is manifested by cutting out the magnetic layer 2 itself in the pattern. That is, the magnetic layer 2 usually has a dark brown or black color, and by making the card base 4 have a color that clearly differs from the color of the magnetic layer 2, such as white, the pattern of the magnetic layer 2 can be changed. The color of the card base 4 located below the magnetic layer 2 can be visually recognized from the missing portion, and thereby the character pattern is revealed on the magnetic layer 2.

By the way, the shape of magnetic cards that are currently widely used is based on the JIS standard, which stipulates that the width of the magnetic stripe, for example, must be 6.2 mm or more. Moreover, since the track width that is actually used for magnetic recording is generally 2 mm, the other widths of 4.2 mm or more are not actually used for recording and reproduction, and the above-mentioned omissions occur in this area. If such a portion is provided, there will be no problem with magnetic storage reproduction. Further, regarding magnetic stripes, those with a width of around 6.5 mm are often used, but if you use a magnetic strip that is slightly wider than this, you can safely provide the missing part with this magnetic stripe. .

Next, one example of a method for manufacturing such a magnetic card will be explained based on FIGS. 2 to 4.

FIG. 2 shows a cross section of the transfer magnetic tape 11, in which a magnetic layer 2' is provided on one surface of a release paper 13 via a release agent 15, and this magnetic layer 2' is a magnetic layer 2'. It has a structure in which a protective layer 14 is laminated on the release paper side with the recording medium 12 in the center, and an adhesive 16 is laminated on the opposite side.

The magnetic layer 2' of the transfer magnetic tape 11 is transferred to a predetermined position on the card base 4 by a thermal transfer method, thereby forming the magnetic layer 2. At this time, as shown in FIG. 3, this transfer magnetic tape 11 is brought into close contact with the card base 4 and is heated and pressed as a mold 21, which corresponds to the shape of the character pattern to be formed on the magnetic layer 2 on the card. A tape having a concave portion 22 provided on the surface in contact with the tape 11 is used. By pressing and heating the transfer magnetic tape 11 onto the surface of the card base 4 using such a mold 21 as shown in FIG.
The adhesive 16 acts to attach the magnetic layer 2' to the card base 4.
Become one with. However, the transfer magnetic tape 11
Since the portion of the mold 21 facing the recess 22 is not pressurized, the adhesive 16 does not act on the magnetic layer 2' and the magnetic layer 2' is not integrated with the card base 4.

Next, as shown in FIG. 4, when the mold 21 and release paper 13 are separated from the card base 4, only the portion of the magnetic layer 2' that faces the recess 22 of the mold 21 and is not heated and pressurized is not transferred. The magnetic layer 2 remaining on the release paper 13 (residual magnetic layer 2'') and transferred to the card base 4 will be missing that part, and as a result, a character pattern will be formed on the magnetic layer 2. become.

Further, the magnetic layer 2 thus formed is generally embedded in the card base 4 so as to be flush with each other by hot pressing in order to improve the smoothness of the card surface.

Although the magnetic card according to the present invention can be manufactured by the method described above, it is clear that the method is not limited thereto and may be manufactured by any other method.

<Effects> The present invention is as described above, and since the character pattern is provided on the magnetic layer by intentionally omitting the magnetic layer itself, it is much more durable than those using conventional printing methods. Furthermore, it is possible to form patterns as clear as printing methods.
