256-channel magnetic imaging system



Fabio C. Da Silva, Sean Halloran, Anthony B. Kos, David P. Pappas


We present the design and fabrication of a magnetoresistive imaging system capable of scanning 256 channels simultaneously along linear ranges of either 4 or 13 mm. High speed electronics read the channels and transfer the data to a computer that builds and displays the images. The system was successfully used to image magnetic tapes for real-time forensic validation purposes and can also be applied to other nonivasive imaging applications.
