Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、磁気カードに関する。[Detailed explanation of the idea] [Industrial application field] The present invention relates to a magnetic card.
従来の磁気カード・磁気テープ等としては、ス

Conventional magnetic cards, magnetic tapes, etc., are either coated with magnetic paint containing lubricants such as phosphate ester, fluorine, or silicone, or coated with lubricant on the surface of the coating to prevent stick slip. There are things that have been painted.
しかし、ヘツド圧の高い条件や走行速度が遅い

つた。
However, under conditions of high head pressure or slow running speed, stake slip was likely to occur.
それ故に本考案の課題は、ヘツドと磁性面との
接触摩擦を小さくし、かつ滑り性及び強度に優れ
る磁気カードを提供することにある。 Therefore, an object of the present invention is to provide a magnetic card that reduces the contact friction between the head and the magnetic surface and has excellent slipperiness and strength.
本考案によれば、磁性面表層に網点印刷を行つ
たことを特徴とする磁気カードが得られる。
According to the present invention, a magnetic card is obtained which is characterized in that halftone dot printing is performed on the surface layer of the magnetic surface.
この磁気カードによると、磁性面表層の網点印

ヘツドその他走行系接触物との間で発生するステ
イツクスリツプが防止される。 According to this magnetic card, the magnetic layer is protected by dot printing on the surface layer of the magnetic surface, and
Stick slips that occur between the head and other objects in contact with the running system are prevented.
第１図及び第２図は本考案の一実施例による磁
気カードを示す。第１図及び第２図を参照して、
非磁性支持体１上に記録用磁性層２を設け、この

1 and 2 show a magnetic card according to an embodiment of the present invention. With reference to FIGS. 1 and 2,
A recording magnetic layer 2 is provided on a non-magnetic support 1, and a very thin flattened printing layer 3 is provided on this magnetic layer by offset printing. The nonmagnetic support 1 is made of polyethylene terephthalate (PET), paper, a plastic board, or the like.
平網印刷層３は第２図Ａ部を拡大した第３図か
らわかるように、磁性層２上で互いに間隔をおい
て隣接した多数の円形の微細な印刷部４の集まり
よりなる。これによるとヘツドとカード表面との
接触面積を小さくできる。 As can be seen from FIG. 3, which is an enlarged view of section A in FIG. 2, the plain mesh printing layer 3 is composed of a large number of circular fine printed portions 4 adjacent to each other at intervals on the magnetic layer 2. According to this, the contact area between the head and the card surface can be reduced.
また平網印刷層３に使用した印刷インキは、主
に酸化重合もしくはUVキユアタイプのものであ

塗膜が得られる。したがつて平網印刷層３は薄く
強い膜となる。こうして得られた膜の堅さがヘツ
ドとの摩擦を小さくする。 The printing ink used for the plain mesh printing layer 3 is mainly of the oxidative polymerization or UV cure type. Therefore, a dense coating film with few pores caused by solvent evaporation can be obtained. Therefore, the plain mesh printing layer 3 becomes a thin and strong film. The stiffness of the film thus obtained reduces friction with the head.
上述の磁気カードによると、カードとヘツドの
接触面積が小さく、かつヘツドと接触する部分の
摩擦が小さくなることで、ステイツクスリツプを

る。 According to the magnetic card described above, the contact area between the card and the head is small, and the friction of the part that comes into contact with the head is small, so that the effect of preventing stick slip can be obtained.Moreover, the thin and strong printing layer 3
also acts as a protective layer. Furthermore, since the pattern is regular and sufficiently fine with respect to the head area, it has almost no effect on modulation, etc. In addition, since the amount of lubricant that is conventionally added to prevent stick slip can be reduced, the composition of the magnetic layer can be simplified.
なお、印刷部４の厚さや形や密度は用途に応じ
て様々に変形可能である。 Note that the thickness, shape, and density of the printing section 4 can be varied depending on the application.
またこの磁気カードはアナログ・デジタルを問

以上述べたごとく本考案によれば、ヘツド圧の
高い厳しい条件でもステイツクスリツプを防止で
き、且つ表面保護等の利点を持つた磁気カードの
提供が可能となつた。 It goes without saying that this magnetic card can be used for both analog and digital cards. [Effects of the Invention] As described above, according to the present invention, it has become possible to provide a magnetic card that can prevent stick slip even under severe conditions with high head pressure and has advantages such as surface protection.
