In the above-mentioned conventional structure, only the arcuate tip of the magnetic card reader / writer device is provided on the sliding surfaces 7, 13 of the recording magnetic head and the reproducing magnetic head. When the use of the magnetic card is increased due to the contact with the recording medium, the reproducing magnetic head is easily worn away, and the core width of the reproducing magnetic head is narrower than that of the recording magnetic head. Since the sliding surface 13 is constituted by the width, there is a problem that the sliding surface 13 of the reproducing magnetic head is more worn than the sliding surface 7 of the recording magnetic head.
