Method and apparatus for optically recording and reproducing information

摘要

An information recording and reproducing apparatus includes an optical head (3) having a super resolution film (6) formed therein. The optical head (3) includes a laser for producing an energy beam (4), a lens (2) for focusing the energy beam (4) and a super resolution film (6) disposed in a position on which the energy beams (4) is focused by the lens (2), whereby recording and reproducing of high-density information is attained.
