Zusammenfassung:	SAFEGUARDING OF DATA RECORDED ON DISK BY TUNNEL ERASE MAGNETIC HEAD ASSEMBLY Apparatus is provided for the safeguarding of data recorded on disk and diskettes by tunnel erase magnetic head assembly which comprise a read/write transducer for magnetically recording data along tracks on said disk and a pair of magnetic erase transducers adjacent to the read/write transducer for limiting the width of the recorded data. The apparatus for safeguarding the recorded data comprises apparatus for sensing the activation of the erase and/or read/write transducer and apparatus responsive to such sensed activation for determining if the activation is erroneous.
