Contamination preventing device of optical head for near field recording

摘要

A contamination preventing device of an optical head for near field recording includes a slider being supported by a suspension in a deck and having a collective hole vertically penetrated though which a light source is transmitted; a collective lens being installed at a lower portion of the collective hole of the slider, collecting light generated from the light source and forming a spot at an upper surface of a recording medium; and a lens contaminant removing means removing a foreign substance clung to the collective lens. When the surface of the collective lens mounted at the slider is exposed to contaminant substances while performing interaction with the surface of the recording medium in the near field optical recording or reproducing, the lens surface can be easily cleansed to remove the contaminant of the surface of the lens immediately.
