摘要： A reader/writer effective in preventing forgery of data recorded in magnetic cards, wherein an erasing head (1) is provided with a reverse current preventing circuit (3) that permits the head current to flow in only a direction in which a magnetic field for erasing data is generated and that prevents the generation of a magnetic field in the opposite direction. As a result, a reader/writer for magnetic cards can be equipped with an erasing head by which data is not rewritten. Therefore, even in case the reader/writer is stolen, it cannot be used for forging data in magnetic cards. Moreover, provision of the reverse current preventing circuit (3) makes it impossible to rewrite data in magnetic cards even if the circuitry associated with the erasing head is modified, and the safety is improved.

摘要： To solve the problems with the prior art, a magnetic card has a laminated structure in which a magnetic layer (3) for data recording is disposed between a substrate (2) for supporting the magnetic layer (3) and a protective layer (4) for protecting the magnetic layer (3). The thickness of the substrate (2) is equal to that of the protective layer (4), and the magnetic layer (3) is disposed substantially at the center portion in the direction of thickness of the data recorded card. Accordingly, the change of the gap of the data recorded on the magnetic layer due to bend of the card can be minimized. Even when the card is bent, therefore, the data can be correctly read and written.

摘要： A reader/writer including a placing base (1) for placing magnetic cards on it and carrying them when reading/writing data. The placing base (1) has a half region (1a) provided on the insertion side whose width conforms with the width of a predetermined magnetic card, and has another half region (1b) on the back side, which is narrower than the region (1a) and whose width conforms the width of another predetermined type of magnetic card. Further, the placing base (1) has supporting pieces, which are erected to the side where the cards are placed, at the side edges of the placing base (1). Magnetic heads (4a, 4b) are provided at the positions corresponding to the magnetic recording regions of the magnetic cards, which conform with the regions (1a, 1b) respectively. Sensors for sensing the magnetic cards are provided at predetermined positions. Thereby, data recorded on the two kinds of magnetic cards different from each other in width can be read/written using only one unit.
