MOSES II is a magneto-optical readout system for forensic investigations. The system enables a fast, non-destructive and reliable visualisation of the magnetic audio tape information. Based on a modular design MOSES II supports the investigation of different audio tapes. The magneto-optical imaging technique allows identifying overwritten tapes. Besides magneto-optical readout an acoustic signal control is possible. This enables a fast detection of remarkable noises, cracks and traces of manipulation in combination with direct, precious and reliable visualisation of such magnetic information.

The full MOSES II - system contains the basis device including sensor unit, optical system and audio tape modules, a high resolution camera technique and digital imaging software.
