For manufacturing security documents, a plurality of security documents are printed on a sheet. The first electrode layer is composed of an inorganic material having an electrical resistivity lower than that of the second electrode layer. An information recipient can configure and dynamically change the manner in which the information is presented, so that relevant information for that recipient can be rapidly digested. This allows the actuator to be lowered into the drive deck in an off-disc position without colliding with the spacer, thereby facilitating in-deck merging of the actuator. The lunch box has a sufficient structural strength and can be manufactured in a cost effective process. The bearing assemblies may include self-contained pressure compensators.
