ABSTRACT:
A system for safeguarding magnetically recorded data. The system includes a housing which carries a turntable on which media containing the data is stored. Sensors are provided for generating destruct signals responsive to attempts to gain unauthorized access to the data. A control circuit responds to the destruct signals for energizing an electromagnet simultaneously with rotation of the turntable so that the media is carried through the electromagnetic field created by the magnet for erasing the data.
