ABSTRACT:
An optical reproducing apparatus for reproducing information on a medium includes a light source, an optical system for irradiating a light beam generated by the light source on the medium, a detector for detecting a reflected light from the medium; and a reproducer means for reproducing information on the medium by using a signal from the detector. The medium is a substrate having grooves and lands alternately formed thereon in a radial direction, which serve as recording tracks and have prepits.
