<p>PURPOSE:To clean the surface of a magnetic head in a simple and sure way and also not to leave any stain of an abrasive material, etc., in a card reader by providing alternately the abrasive and adhesive layers on the surface of a card base material. CONSTITUTION:SiO2 powder, i.e., an abrasive material 3 and a silicone adhesive 2 are alternately applied on the magnetic stripes of a general magnetic card. Accordingly, both abrasive and adhesive layers alternately pass the surface of a magnetic head with use of a cleaning card. As a result, the surface of the magnetic head is surely cleaned and the used material 3 and the stains are surely adsorbed by the adhesive 2 and never remain in a card reader. In this example, the material 3 and the adhesive 2 are applied to only a part that touches the magnetic head in the defined card inserting direction. However these material and adhesive can be applied to the entire surface of the card in stripes. In this case, the card inserting direction is not defined to be in a single direction but in two directions. Thus, the service life of the cleaning card is approximately doubled.</p> |
