Abstract
An information recording and/or reproducing apparatus records and reproduces information with probes. The apparatus includes probes made of an elastic body, a recording medium which oxidizes in portions where an electric current flows in the atmosphere to form recording bits, a device for moving the probes relative to the recording medium, and a device for applying a recording voltage between the probes and the recording medium for forming the recording bits.
