MAGNETIC-RECORDING-MEDIA PROCESSING DEVICE AND METHOD FOR CONTROLLING MAGNETIC-RECORDING-MEDIA PROCESSING DEVICE

摘要

There is provided a magnetic recording medium processing apparatus and a control method of the magnetic recording medium processing apparatus capable of reducing the influence on the reading of magnetic data of the magnetic recording medium processing apparatus and reliably preventing unauthorized acquisition of magnetic data . A reference potential portion 522 and a resonance circuit in which an inductor L51 and a capacitor C51 are connected between the first node ND52 and the second node ND53, A resonance section 511 which resonates in a state where the second node is connected to the reference potential section 522 to generate a magnetic field and a resonance section 511 which is connected between the second node ND53 of the resonance section and the reference potential section 522 And a resonance driving unit 523 including a driving switching element DSW51 for switching between a conductive state and a non-conductive state in accordance with the control signal CTL and switching between a connection state and a non-connection state of the second node of the resonance part and the reference potential part .
