AbstractHigh resolution magnetic mapping is a technique that has shown great value in the forensic evaluation of magnetic audio recording tapes. The use of single element raster scan systems has shown that the technique has promise in diagnosing many other systems where internal currents or magnetized inclusions generate external measurable fields. NIST has developed a 256 channel MR array sensor that has significantly increased the data collection rate for 2D magnetic field scans, with high resolution compatible with forensic evaluation of audio magnetic tape. ARC believes that if a system is established that can demonstrate the diagnostic ability of magnetic imaging with high resolution and high data capture rate on samples including and beyond recording tape of government and commercial interest, then a market might be created for an integrated turnkey system following the business model for AFM systems.
