A method of forming a slotted substrate that includes patterning a thin film over a substrate so that at least a portion of the substrate within a slot region is not covered by the thin film. The biomaterials exhibit biological activity after patterning. The collection is partitions the collection into buckets. As such, a dynamic multiplexing regime may be implemented. The smart card also comprises intelligent agents, called script translators, and a virtual file management system cooperating with a specialized script-translating intelligent agent. Reproduction of the optical disc is performed by switching effectiveness and ineffectiveness of a function of splitting the light flux of the optical element, and adjustment of an outgoing laser power is performed.
