Dendritic metal nanostructures made using a surfactant structure template, a metal salt, and electron donor species. The incoming clutch unit is closed after performing a filling operation for providing a filling pressure for the incoming clutch unit. The first and second plates are positioned beside one another to form the power contact. Displacing the membrane to a first position causes the gap to be filled with an index-matching liquid such that light from the first input waveguide is transmitted to the first output waveguide. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data. In combination, the angled flux interaction surfaces and the angled magnetic surfaces define air gaps.
