An optical disk, it includes: Continuous information tracks formed by land/groove traces are rowed into land/groove single spiral shape on optical disk. During each revolution, each land trace is connected to adjacent groove trace at connection point, for alternately forming land and groove trace into continuous spiral. And the optical disk is divided into plural annular zones, and each revolution of information recording trace belongs to one of zone band by based on position of trace at radical direction. And each revolution of information recording trace is divided into plural information records at sector of unit length in scanning direction. The head of each sector on optical disk has a head portion. The head portion includes recognition pattern that is formed by data, which is not used as information part or a sequence of pits having address.
