ABSTRACT:
A method for recording and/or reproducing images includes a step of performing a two dimensional scanning on a recording medium with a probe electrode which relatively returns in the X direction for the main scanning and in the Y direction for sub-scanning. The main scanning of the probe is performed at a frequency which is one positive integerth of the horizontal synchronous frequency of the image signal so as to enable the period required for returning of the probe electrode to be matched with the blanking period of the image signal. Thus, it is possible to avoid any data recording and reproducing operations during the period required for returning of the scanning probe electrode.
