Historically valuable film material, dating from the first half of the last century, is prone to decay. A non‐contact magneto‐optical method according to Faraday was used by MWA’s development partner 5micron GmbH to directly read the magnetization in the tape as an imaging of the magnetic signature (patent pending). For this purpose MWA has developed a special winding table which integrates the revolutionary sensor system and enables the evaluation of the analogue waveform over the entire length of the tape. The sensor system will be integrated into existing film copying tables or future digitization or restoration systems. All main octaves (six main octaves corresponding to 125 Hz to 8000 Hz) can be captured, mapped, corrected, and reproduced.
