Title: Magneto-resistive Field Mapping of Analog Audio Tapes for Forensics Imaging
Published: June 02, 2008
Abstract: Magneto-resistive imaging of cassette tapes for forensic analysis applications is presented. Sample tapes were recorded on various tape recorders with events typically encountered in investigations. A comparison of the images with those obtained using ferrofluid is presented, along with comparisons of multiple instances of the same event with the various recorders.
