Device for contactless optical playback of information during recording or reproduction from a record carrier with recording tracks

摘要

The optical scanning device has a light source (3) directing light onto the recording track (2) and a detector (4) for detecting the light reflected by the latter, with a beam splitter (5) and a lens (6) inserted in the light path between the light source and the detector. A micro-mirror (7) is inserted between the light source and the beam splitter, with its mirror surface deflected and/or pivoted via a drive (8), to adjust the incidence point and/or the incidence angle of the light beam.
