An improved method and apparatus for STEM sample preparation and analysis. In addition, the method can include applying at least one front perspective filter to each of the left and right front audio signals to yield filtered left and right front output signals, where the left and right front output signals each drive a front speaker. When write current is passed through the current strip heat is generated at the edge of the strip and a magnetic write field is induced at the disk surface. A pulling device is attached by a line to the roller quadrant. The generating of the virtual article, the marking of the physical materiality, and the tagging of the virtual article occur at substantially the same time. A lower electrode may be formed through the second mold layer and the first mold layer pattern.
