摘要：
A reproducing apparatus for reproducing information from recording elements formed with very small pits on a planar surface. The reproducing apparatus includes a probing unit positioned at a very small distance apart from the surface of the recording element and a scanning unit for scanning the probing unit at a very small distance apart from the surface of the recording element. The reproducing apparatus also includes a detecting unit connected to the probing unit and the recording element respectively, for detecting interactions generated between the probing unit and the surface of the recording element and a regeneration unit connected to the detecting unit for inputting a signal output from the detecting unit and for regenerating information by detecting a pattern of the pits by the input signal.
