Abstract
A magnetic recording medium processing device may include a magnetic recording medium insertion slot; a medium pathway connected to the magnetic recording medium insertion slot; a magnetic head arranged to face the medium pathway; and an interference magnetic field generating device structured to generate interference magnetic fields outside the magnetic recording medium insertion slot. The interference magnetic field generating device may include a coil, a capacitor, a first power line, a second power line to which a voltage different from that to the first power line is applied, multiple switches structured to switch the connections between the first power line and the second power line of the coil and the capacitor, and a switch control unit structured to control the multiple switches.
