PROBLEM TO BE SOLVED: To provide a magnetic recording medium processor that can reduce an influence on the reading of magnetic data of the magnetic recording medium processor and surely prevents illegal acquisition of the magnetic data; and a method for controlling the magnetic recording medium processor.SOLUTION: A magnetic recording medium processor includes: a drive power supply unit 521 that supplies a drive voltage VCC; a reference potential unit 522; a resonance unit 511 that includes a resonance circuit, in which an inductor L51 and a capacitor C51 are connected between a first node ND52 and a second node ND53, receives the drive voltage at the first node, and resonates and generates a magnetic field in a state in which the second node is connected to the reference potential unit 522; and a resonance drive unit 523 that includes a drive switching element DSW51 which is connected between the second node ND53 of the resonance unit and the reference potential unit 522 and is switched between a conduction state and non-conduction state according to a control signal CTL, and which switches between a connection state and a disconnection state between the second node of the resonance unit and the reference potential unit. |
