Method and apparatus are disclosed to enable secure archiving and backup of data with reduced risk of data lost. A sample embodiment of the method comprises the steps of determining graphical layers, steps, and image processing parameters for creating an image. The document elements include multiple content elements and one or more presence elements. For example, the polarization of the laser beam may be rotated to correspond with the alignment of a link in a semiconductor device to be cut by the laser beam. The milling tips are constituted by ceramic cutting tips. According to the invention, at least one waveguide has a reduced cross-sectional area in the crossing region andor at least one waveguide is routed locally at an increased crossing angle relative to the other waveguide in the crossing region.
