Magneto-resistive Field Mapping of Analog Audio Tapes for Forensics Imaging

Published

Author(s)

David P. Pappas

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.
