ABSTRACT:
The invention provides an image forming medium and method, and a recording and playback apparatus in which signals can be recorded on the medium sequentially, similar to a magnetic tape or the like, or simultaneously two dimensionally, similar to a photographic film. The recording medium includes a laminate formed on the surface of a semiconductor substrate having a conductive layer on the undersurface thereof. The laminate is formed of an oxide film, a nitrided film, a photoconductive semiconductor layer and a transparent conductive layer. For recording, an optical image is directed onto the transparent conductive layer while applying a predetermined potential between the transparent conductive layer and the conductive layer.
