ABSTRACT:
A reproducing apparatus for reproducing information recorded on an optical recording medium including a disk-like substrate, a spiral or concentric-shaped groove structure along a track formed on the substrate, and the groove structure being wobbled in a radial direction of the medium. The track is divided into a plurality of recording units in the track direction by at least one radial boundary line formed by a dropout portion, wherein identification information is disposed in the track at a head of each recording unit at the dropout portion. The apparatus includes an irradiation source for irradiating a light spot on the optical recording medium, an optical detector for detecting a reflected light from the medium, and a reproducer for reproducing information by using a signal from the detector.
