Magneto-Optical Tape Scanner for Degraded Archival Magnetic Media (Revision 5.2)
Discipline: Signal Archaeology · Lead Researcher: Dr. Evelyn O'Connor
OPERATIONAL ABSTRACT
An optical scanner utilizing the magneto-optic Kerr effect to read magnetic flux lines on degraded vintage tape loops without physical head friction. Enhanced revision 5 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Polarized laser light reflected off the tape's magnetic emulsion experiences polarization rotation proportional to surface magnetization, extracting audio without physical wear. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
