A distance-controlled tunneling transducer comprises a plurality of tunnel tips arranged in an array at a tunneling distance from an electrically conductive surface of a storage medium. Each tip is attached to a respective cantilever beam permitting the distance between each tip and the surface to be individually pre-adjusted electrostatically. Arranged in juxtaposition with each cantilever beam is an active control circuit for adjusting the tip-to-surface distance during operation of the storage unit, thus preventing crashes of the associated tip into possible asperities on the surface of the recording medium. Each control circuit is designed such that its operating voltage concurrently serves to pre-adjust its associated cantilever beam and to maintain the tip-to-surface distance essentially constant.
