A magnetic tunnel junction device and fabrication method is disclosed. Synchronizing pulses associated with a video signal to be recorded are analyzed to determine whether a video signal is present and, further, to determine whether the video signal is not distorted. An overall image of the imaging region is displayed and if any components to be added appear, the kinds of these components are identified and quantitative data on each kind of component is registered. An interface converteradapter converts a standard mini-PCI Express slot into a specialized mini-PCI Express slot with voice capabilities. In the image forming medium, irradiation of the imaging layer cause the photobase generator to generate a base that reacts with the coupling agent to produce an image. The cutting elements on the circular blade may be substantially U-shaped elements equally spaced about the periphery of the substantially circular blade.
