Abstract:
An information recording apparatus, comprising:a probe disposed in a position opposed to a recording medium;a capacitor;a first switch arranged between, and connecting, said probe and said capacitor;a DC power supply supplying charge to said capacitor;a second switch, arranged between and connecting said capacitor and said DC power supply; anda control circuit controlling opening and closing motion of said first and second switches with reference to a recording signal,wherein said control circuit first sets said second switch closed when said first switch is open so that the charge supplied from said DC power supply is stored in said capacitor, and then said control circuit turns said second switch open and turns said first switch closed so that the charge stored in said capacitor is applied as a voltage between said probe and said recording medium, thereby recording information.
