An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. Metal nanopins are fabricated on a metal foil by capillaritron plasma source dry etching. In one example, the data interface conforms to the Digital Visual Interface specification. Values stores in PIRs may control access to associated CAM entry sets andor be output in response to predetermined operations in an associated CAM entry set. In addition, the algorithm makes adjustments to the zone boundaries based upon a misalignment between the centers of the lens being used and the APS array. Also provided are systems and methods of using the, for example electrochemical, analyte determining devices in analyte monitoring.
