ABSTRACT:
A method for capacitatively storing data on a grooveless storage device is provided. The storage device is comprised of a conductive substrate having a layer of a photosensitive composition which dielectric constant is varied in the presence of irradiation. The method is carried out by exposing a layer of a photosensitive composition to irradiation in a predetermined pattern. The exposed layer is fixed by heating. Video disks for recording and playing back video signals can be prepared in accordance with the present method.
