A controller in an optical disc processor serves as a visual information recording unit for recording visible information by forming visual information-display pits to be closely aggregated together in a given display pattern, the visual information-display pits having a width larger than that of other pits, wherein the title information is contained in a TOC to be recorded on an optical disc. The visual information-display pits are formed on a recording layer closest to a base layer and different from a recording layer on which to form encoded data pits. This makes it possible to record visible information on the optical disc without requiring a user to separately input data for visual information recording.
