Abstract: A card reader performs a reading operation of reading magnetic data by scanning the magnetic data in a first direction and a writing operation of writing the magnetic data by scanning the magnetic data in a second direction. Prior to these reading operation and writing operation, a head moving mechanism performs a preparatory operation of moving a magnetic head positioned in a head retracted position to a head contact position and a preliminary operation of moving the magnetic head slightly (e.g., about 1 mm) in the same direction as a scanning direction when the reading operation and the writing operation are performed. By performing the preliminary operation, even if a backlash caused by wearing due to use, gaps present for reasons of design, or the like increases and an unloaded area increases, a phenomenon that the head moving mechanism 8 operates unloaded during the preliminary operation can be eliminated.
