Optical recording medium, method for reproducing information signals recorded on the optical recording medium and data recording device employed for producing the optical recording medium.

摘要

There is provided an optical recording medium (1) including a first pit string having a succession of pits (P) and mirror surface sections (M), which first pit string is formed on one side of a track center (Tc) as a reference, and a second pit string having pits (P) and mirror sections (M), reversed in their array from the pits (P) and the mirror surface sections (M) of the first pit string. A laser beam (L) is radiated onto the track center (Tc) for accessing information signals represented by the pits (P) and the mirror surface sections (M). There are also provided a recording device and a reproducing device for such optical recording medium (1).
