A magnetic recording medium is disclosed that includes a substrate; an anodic alumina film formed on the substrate; a pore formed in the anodic alumina film; a carbon layer covering the surface of the anodic alumina film and the inner wall of the pore; a magnetic particle formed on the carbon layer inside the pore; and a lubrication layer covering the carbon layer and the magnetic particle. The system can be of the distributed type wherein the condenser and compressor may be coupled to service a group of adjacent refrigeration cases, wherein each case would have its own evaporator. Dimethyl sulfone may be almost completely removed from compacts pressed from tantalum, etc. In the case of more than one protected paths, the failed path is identified by means of the unique trail trace identifier received on the protection path. In some embodiments, the anchor includes a connector coupling a fixed portion to a removable portion. In a further non-limiting example, a server computer coupled to a communications network transmits to the client computer, computer-executable instructions for generating and displaying a graphical user interlace.
