Abstract

A METHOD OF CLEANING A MAGNETIC HEAD (1) OF A DEVICE FOR READING AND/OR WRITING A MAGNETIC TRACK DISPOSED ON A MEDIUM (10) SUCH AS A CARD MADE OF PLASTICS MATERIAL OR A TICKET MADE OF CARD OR OF PLASTIFIED CARD, SAID DEVICE INCLUDING AT LEAST ONE MAGNETIC HEAD (1), A PRESSER WHEEL (2), AND A DRIVE ASSEMBLY (4 TO 9) FOR DRIVING SAID MEDIUM TOWARDS SAID MAGNETIC HEAD (1), THE METHOD BEING CHARACTERIZED BY THE FACT THAT WHEN IT IS DESIRED TO CLEAN SAID MAGNETIC HEAD (1), SAID MEDIUM (10) IS CAUSED TO PERFORM A SUCCESSION OF GO-AND-RETURN DISPLACEMENTS SO THAT THE LEADING EDGE (11) OF SAID MEDIUM (10) JUST ENGAGES THE APEX OF THE HEAD (1) A NUMBER OF TIMES THAT IS SUFFICIENT TO CLEAN IT.
