A process for patterning a substrate by forming electrodeposited layers on the substrate so as to correspond with two or more kinds of patterns has the steps of preparing an electrodeposition original plate having conductive patterns respectively corresponding with patterns in which respective conductive patterns are laid bare and conductive patterns are insulated from each other in such a manner that the electrodeposited layers can be respectively independently formed on the conductive patterns successively, forming the electrodeposited layers on the respective conductive patterns and transferring the electrodeposited layers formed on the respective conductive patterns, to a substrate.

Patterning process, process for producing optical recording medium, and

An optical recording medium provided with a substrate has a preformat on the surface thereof, a recording layer, and a protecting layer. The substrate has an electrodeposit layer arranged in a pattern corresponding to the preformat on the surface of the substrate.
