Abstract

A technique for preventing alteration of a magnetic ROM card. Magnetic signals are recorded on the ROM card through a process in which a magnetic recording layer is formed by applying magnetic coating to the surface of a substrate, magnetic signals are written on the magnetic recording layer while the recording layer is undried, and the written magnetic signals are fixed by drying the recording layer immediately after the magnetic signals are written. The magnetic signals are the signals representing the number of uses. When the magnetic signals are written while the magnetic recording layer is undried, the magnetic signals cannot be erased nor rewritten. Since the magnetic signals are the signals representing the number of uses, this magnetic ROM card is especially suitable for a prepaid card. Therefore, the magnetic ROM card which cannot be altered and falsely used is especially suitable for prepaid cards. It is also possible to fix the magnetic signals recorded on both ends of the magnetic recording layer or to fix one or more intermediate magnetic signals in addition to the magnetic signals at both ends of the magnetic recording layer and not to fix the other magnetic signals.

In order for a ROM card to be used as a pre-paid card, it must be of an age that can be referred to as a frequency signal, such as spectators, a possible number of cranes, and the ability to speak as such (1). Such a frequency signal is expressed as S. The ROM card has a certain amount of money every time. It is suitable for telephone cards and pachinko cards.
更に、本磁気 ROMカードの の靈、 ±15®定化された度数信^ ^ さ れていた部分の觸^!を、 パンチ穴開け、研磨その他の機觀破 か、 ¾ ¾破壊その他の電¾ ^法で破壊するのもよい。 このように、磁気言 層自体 を破壊す ま'、 その後磁^!^ ¾を することカ^:に^ r能となり、  In addition, the touch of the part of the magnetic ROM card where the ± 15® standardized frequency signal ^ ^ was applied is punched, polished or otherwise observed, or ¾ ¾ It is good to destroy by the ¾ ^ method. In this way, the magnetic layer itself is destroyed, and then the magnetism is reduced to ^ r.
OMカードの不正使用を防止せんとする本発明の目的により一層沿ったものとな る。  This is more in line with the object of the present invention to prevent unauthorized use of the OM card.
また、 本発明の S¾^ROMカードは、 M -^o^ の方法で 麵 化されるように躯み、他 分を 方法で额ぇ可能 に書込も もある。  In addition, the S の ROM card of the present invention is structured so as to be modified by the method of M- ^ o ^, and there is also a case where other parts can be written by the method.
このような磁気 R OM力一ドは、 ブリぺ一ドカ一ドの 1回の使用当たりの度数 の ，一 ¾m に特に鶴である。  Such magnetic ROM force is especially crane at a frequency of about 100 m per use of the bridge card.
この齢、鶴え可能に まれた度数信号の最初と最後に、 それぞれスター トマ一クとエンドマークを設け、 このスタートマークとエンドマークを固定化す るように書込みを ί亍ぅ。 このような S^ROMカードは、 プリぺードカードの使 用により、 度数信号 TIS^される鶴が 0になったときに、 ±ie@定化されたス タートマークとエンドマークを謹すると 的である。 このように ま'、磁 m m( m ι回で済み、 そして ^済みの II R OMカードの不正^も ^に防止できる。  A start mark and an end mark are provided at the beginning and end of the frequency signal that can be placed at this age and crane, respectively, and writing is performed so that the start mark and the end mark are fixed. Such S ^ ROM cards are designed to use ± ie @ standardized start mark and end mark when the crane applied to the frequency signal TIS ^ becomes 0 by using a pre-read card. It is. In this way, it is possible to prevent the illegal use of the II ROM card that has been completed by using the magnet mm (m 回 times).
また、 最初と最後のそれぞれに、 固定化したスタートマークと エンドマークを設け、更に、 スタートマークとエンドマークの間に、 1つ の 固定化した中間マークを設けてもよい。 この^、プリべ一ドカードが予め定め た一定の度 tS^fflされる度に、 ±1己スタートマ一クから順次中間マークを破壊 し、残高が 0になったときにエンドマークを破壊するようにする。  Also, a fixed start mark and end mark may be provided at the beginning and end, respectively, and a fixed intermediate mark may be provided between the start mark and end mark. Every time the pre-paid card is tS ^ ffl, the intermediate mark is destroyed in order of ± 1 from the start mark, and the end mark is destroyed when the balance becomes 0. To do.
尚、以上 の ¾¾¾を可能とするために、 の ROMカードに 用 、て 、た鶴リ一ダライタ i ¾ ^手 しくは な手段により麵 層を破壊するための 58 ^段を設けたリ一ダライタを、本発明の磁気 ROMカー ド用のリ一ダライタとして用いる。  In addition, in order to make the above-mentioned operation possible, a T-Tsuru reader / writer with a 58 ^ step for destroying the layer by hand or other means is used for a ROM card. Is used as a reader / writer for the magnetic ROM card of the present invention.
