Abstract

PURPOSE:To improve signal quality by providing headers between grooves and grooves for guiding tracks so that the sections to be changed in state by photoirradiation are the grooves for guiding tracks. CONSTITUTION:The headers 12 are provided between the grooves and grooves for guiding tracks so that the sections to be changed in state by photoirradiation are the grooves for guiding tracks. Namely, a laser beam for control is tracked to resist parts 14 and a laser beam for recording, reproducing and erasing is tracked to pregrooves 11, by which the erasing, recording, reproducing, random accessing, etc., are enabled. A change of the rugged pits storing information on groove addresses and sector addresses, etc., by writing of data is obviated and the pits are usable as address signals even after the writing of the data if this optical recording medium is used. The signal quality is thereby improved.
