A method of storing data in a storage device.

摘要

This invention relates to a method of capacitatively storing data on a grooveless storage device. The storage device is comprised of a conductive substrate having a layer of a photosensitive composition whose dielectric constant is varied by exposing it to light. The method is carried out by projecting light in a predetermined manner onto the surface of said layer to effect changes in the dielectric constant of said layer in the predetermined manner. 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.
