When information signals are recorded on an information signal recording medium formed with circular information signal tracks, the information signals are recorded after being scrambled with scrambling signals of cyclic codes. The period at which the scrambling signal makes a round is determined longer than a time length of an information signal quantity recorded on the maximum recording capacity (e.g., the outermost tracks), or a part of the scrambling signals are used repeatedly. The information signal recording method can remove the correlation between the adjacent tracks, and thereby enable a stable tracking control.
