Patent ID: 8102362

Claim:
A system for writing a bistable media, the system comprising: the bistable media, including: a substrate; two or more discrete write areas on the substrate, each write area comprising first and second conductors and a bistable material layer interposed therebetween, the second conductor of each write area having been patterned into a plurality of contacts so as to form a plurality of individual electrical areas, the bistable material layer being selectively operable in a transmissive mode or a reflective mode; and at least one media alignment feature on the substrate, the at least one media alignment feature comprising at least one of one or more perforations, indentations, protrusions, switches or jumper wires, the at least one media alignment feature being arranged in a spatial relation to the two or more discrete write areas; and one or more writeheads movable relative to the bistable media, each writehead being configured to interact with the two or more discrete write areas and comprising: one or more electrodes that, for each write area, are configured to contact the contacts of the second conductor and provide power to the first conductor and selective ones of the contacts of the second conductor so as to form an electric field therebetween, and a writehead alignment feature configured to interact with the at least one media alignment feature to align the electrodes of the writehead with the bistable media, the writehead alignment feature comprising at least one of one or more perforations, indentations, protrusions or conductive leads.
