摘要

A recording and/or reproducing and/or erasing apparatus comprises a recording medium (101); a probe electrode (102; 1002) disposed in opposition to said recording medium; and means (112; 1012) for applying a writing, reading or erasing voltage across said recording medium and said probe electrode; characterised by a feedback loop (106, 111; 1006, 1011) arranged to maintain either the distance between said recording medium and said probe electrode substantially constant or arranged to maintain a substantially constant current flowing between said recording medium and said probe electrode. The invention also includes an apparatus for recording and/or reading and/or erasing data, comprising a recording medium (101) and a probe (102; 1002) for recording information onto said recording medium or reading information from or erasing information from said recording medium, and means (102, 1002) for detecting the presence of a track on said recording medium. <IMAGE>
