Abstract
A scanning magneto-resistive (MR) microscope was developed for high resolution imaging of magnetic tapes and digital media. Second harmonic detection was used to remove thermal anomalies. We were able to image sufficient lengths of tape for authentication purposes and for data recovery from damaged samples. The second harmonic technique provides high contrast magnetic images of the magnetic storage media using high resolution MR sensors from commercial hard disk drives. These images can be directly converted into the originally recorded analog audio waveforms or digital data.Citation
